1 - This is, as stated in the title, concerning Gold level difficulty. Silver and Bronze are a completely different story.
2 - Snipers in Gold should not be shooting for the little targets (soldiers, cannibals, etc..) after wave 2 as there will be much more important targets to take down and your ever-present Engineers, Vanguards, Adepts, and Sentinels are much more efficient at killing the little guys with their high-damage AoE powers and combos.
3 - This is assuming that the individual using the guns is capable of getting past the 0.25 second delay on the Javelin and doesn't require 3 attempts to actually hit a target. If you miss 1-2 of your Black Widow shots and can't adjust to the 0.25 second delay you probably shouldn't be using either gun.
For the sake of time, simplicity of the math, and the fact that cloak is the only common demoninator between all infiltrators I will only be using reload-canceling and cloak-damage-enhancements as variables outside the guns themselves. This experiment will feature flat DPS calculations, TtK on an Atlas, and TtK on a Geth Hunter as well as damage lost through shield-gating and armor reduction and damage lost through overkill. The Atlas and Geth Hunter were chosen because the health/armor/shield values are readily available to all through the multiplayer balance thread. Both guns will be assumed at rank 1. Headshot multipliers (used on the Geth Hunter) will be assumed at a 2.5 multiplier as posted by an individual in this thread. Cloak damage multipliers will be assumed 2.3 (1.0+0.5+0.4+0.4) based on taking the additional sniper rifle damage point from cloak. Reload-cancel-times and average times in between shots will be using Specter, I hope he doesn't mind, as the base for the Black Widow, and my team's sniper as the base for the Javelin. Given the wide-spread availability of spare thermal clips and the ease-of-access to ammo crates on most levels we will assume that ammo isn't a problem. It is important to note that both the Javelin and the Black Widow have the same number of spare reloads even though the Black Widow has a higher actual ammo count.
Now, on to the basic DPS calculations.
Black Widow:
Damage per Shot - 514.1
Cloak Damage per Shot - 1182.43 (514.1 * 2.3)
Time Inbetween Shots - 1.15 (based on Specter) (0.15 to aim + 1.0 for RoF)
Reload Time - 1.15 (based on Specter)
Total Iteration - 3.6 ((3 * 0.15) + (2 * 1.0) + 1.15)
Total Iterations per Minute - 16.6667 (60 / 3.6)
Total Damage per Iteration - 3547.29 (1182.43 * 3)
Total Damage in a Minute - 59121.6182 (3547.29 * 16.6667)
Optimum Damage per Second - 985.3603 (59121.6182 / 60)
Javelin:
Damage per shot - 1030.5
Cloak Damage per Shot - 2370.15 (1030.5 * 2.3)
Time Before Shots - 0.36 (based on our sniper)
Reload Time - 1.18 (based on our sniper)
Time Inbetween Shots - 1.54 (1.18 + 0.36)
Total Iteration - 3.08 (1.54 * 2)
Total Iterations per Minute - 19.4805 (60 / 3.08)
Total Damager per Iteration - 3400.65 (1030.5 + 2370.15)
Total Damage per Minute - 66246.3623 (3400.65 * 19.4805)
Optimum Damage per Second - 1104.106 (66246.3623 / 60)
In a perfect situation the Javelin wins the DPS race by 118.4757 or 10.7304%. Obviously this perfect situation is extremely unlikely to ever actually occur, so lets compare these guns against the aforementioned mobs.
Lets start with the Geth Hunter:
For the sake of consistency lets assume that every shot is a headshot.
Health - 2025
Shields - 2278
Black Widow:
Headshot Damage - 2956.075 (1182.43 * 2.5)
Damage Lost to Shield-Gate - 678.075 (2956.075 - 2287)
Damage Lost to Overkill - 931.075 (2956.075 - 2025)
Total Damage Lost - 1609.15
Time to Kill - 1.3 (2 * 0.15 + 1.15)
Javelin:
First Headshot Damage - 5935.375 (2370.15 * 2.5)
Second Headshot Damage - 2576.25 (1030.5 * 2.5)
Damage Lost to Shield-Gate - 3647.375 (5935.375 - 2278)
Damage Lost to Overkill - 551.25 (2576.25 - 2025)
Total Damage Lost - 4198.625 (3647.375 + 551.25)
Time to Kill - 1.9 (0.36 + 1.54)
Quite obviously the Black Widow is far more efficient at killing smaller mobs. It kills a Geth Hunter 31.5789% faster with 61.6744% less damage lost to the shield-gate and overkill while still having a round in the breach for a third shot on a different target.
Next lets compare against the Atlas:
For the sake of consistency we'll assume that every shot is to the main cockpit and thus does normal damage.
Armor - 21094
Shields - 21094
Black Widow:
Damage to Armor - 1132.43 (1182.43 - 50)
Total Damage to Armor per Iteration - 3397.29 (1132.43 * 3)
Iterations to Drop Shields - 5.9465 (21094 / 3547.29)
Iterations to Drop Armor - 6.209 (21094 / 3397.29)
Shot that Drops Shields - 3 (3 * 0.9456) *rounded
Shot that Drops Armor - 1 (3 * 0.209) *rounded
Damage Lost to Shield-Gate - 189.78 (3547.29 - (3547.29 * 0.9465))
Damage Lost to Overkill - 710.1046 ((0.209 / (1 / 3)) * 1132.43)
Damage Lost to Armor - 931.35 (6.209 * (50 * 3))
Total Damage Lost - 1832.2346 (189.78 + 710.1046 + 931.35)
Time to Kill - 43.7599 (((5.9465 * 60) / 16.6667 ) + ((6.209 * 60) / 16.6667))
Javelin:
First Shot Damage to Armor - 2320.15 (2370.15 - 50)
Second Shot Damage to Armor - 980.5 (1030.5 - 50)
Total Damage to Armor per Iteration - 3300.65 (2320.15 + 980.5)
Iterations to Drop Shields - 6.2029 (21094 / 3400.65)
Iterations to Drop Armor - 6.3908 (21094 / 3300.65)
Shot that Drops Shields - 1 ((1 - 0.2029) < (2370.15 / 3400.65))
Shot that Drops Armor - 1 ((1 - 0.3908) < (2320.15 / 3300.65))
Damage Lost to Shield-Gate - 1171.0192 (((2370.15 / 3400.65) - 0.2029) * 2370.15)
Damage Lost to Overkill - 724.2053 (((2320.15 / 3300.65) - 0.3908) * 2320.15)
Damage Lost to Armor - 639.08 (6.3908 * (50 * 2))
Total Damage Lost - 2534.3045 (1171.0192 + 724.2053 + 639.08)
Time to Kill - 38.7886 (((6.2029 * 60) / 19.4805) + ((6.3908 * 60) / 19.4805))
From this we can see that The Javelin is faster by 4.9713 seconds or 11.3604% at killing the Atlas while the Black Widow loses 702.0699 or 27.7027% less damage due to overkill, shield gating, and armor reduction. In practical situations, time to kill is all that really matters on large targets putting the Javelin ahead on large targets by roughly 11%.
That being said, the Black Widow was close. It is also important to note that the Black Widow will have 2 rounds left in its clip after finishing off this Atlas whereas the Javelin could do this through wall(s), the floor (in the case of multi-tier stages), and cover. It comes down to this: As a do-it-all rifle the Black Widow wins due to the speed and efficiency of handling small targets. As a boss hunter the Javelin wins based on the time taken to drop them. The Black Widow favors a more aggressive combat style through it's multi-shot capability and lighter weight while the Javelin favors a more defensive style due to it's object-penetration capabilities and shorter (though not by much) time out of cover. My team's sniper does recommend bringing a side-arm along with your Javelin when using it due to the inefficiency when dealing with small targets. He favors a Mattock 10. I would also like to mention that due to the cooldown mechanics of Cloak when using a Cloak->Immediatly-Fire combo weight doesn't matter. You will have the same cooldown with a Javelin + Claymore as you will with a Carnifex pistol. This has been tested and verified by many individuals other than myself.
Edit - This post has been edited from it's original form to a much more detailed, and hopefully accurate, comparison that I originally posted on page 5.
Edit 2 - Updated to reflect a mathematical error pointed out by Nasu no Yoichi.
