Then there would be all the others... Volus apart, they're all pretty decent kits.
Volus Adept + CSMG + Incendiary Ammo .... yeah, OK, playing the gun not the kit.
However, whenever I've played the VolDept with at least one decent player I'm always pleasantly surprised as just how fast bosses go with with triple orb debuff and being able to go toe-to-toe with Banshees (granted, on a ramp) never gets old 
He plays more like the ColDept than anything else - but without the gigantic green orbs of death he's far more reliant on detonating ammo/powers.
To return to the OP though...
Adepts in general ... anything that relies on Biotics with travel time (ye olde Warp > Throw combo for instance) is in for a certain degree of frustration vs Cerberus or Geth (side-hop dodge). Guns generally trump DoT powers so things like Dark Channel are pretty much just there to complement shooting things rather than killing them outright... and Pull, well, it can be useful up to about Gold level where there's nearly always something unshielded/unarmoured that you can take out of the equation.
The Drell excels in practically any situation - there's not much that can't be solved with Reave > Cluster Grenades.
The Batarian isn't far behind but is more focused on boss-killing; Warp debuffs a single target and gets a BE bonus but it can be dodged.
The Fury is arguably as good as the Drell but instead of relying on grenades she is the grenade! Run at stuff to prime with AF and detonate with Throw to the face at point blank range... BOOM! High risk, high return.
The AA excels against Cerberus, especially with a stagger weapon to ensure Warp > Throw connects. Stasis to screw over Phantoms.
The vanilla humans are really good against Reapers and Collectors and with Warp > Shockwave have the most powerful BEs.
The Krogan Shaman, again, best against Reapers and Collectors but allows for much more in-your-face gameplay. Warp and run at your target, heavy melee and then Shockwave at point blank! Slap a Piranha on him and he's my favourite adept in Platinum.
The ex-Cerbie is also good against Reapers/Collectors - actually, he's an armour murdering machine if you spec him that way.
Which just leaves the Justicar, the Volus and the ACA which are all slightly special cases, they don't necessarily play like you'd expect adepts to play.
The Justicar is an oddity, she can basically run as a biotic weapons platform. Pull has very little cooldown and is situational. Biotic Sphere is somewhat situational you're not going to be spamming it to get detonations (though a tactical charge into a mob, drop sphere, slide back and detonate with Reave often works wonders). So, Reaving and shooting a lot it is then - pack a decent gun (though I totally ignore my own advice and use a Disciple - because lore or something).
The ACA is another serious oddity - there are so many ways to spec the bug from full out PPR wielding weapons platform (Seeker Swarms set for damage reduction), to a kind of biotic sniper with a CSR or a full-blown biotic with a CSMG (and Expert package to help with the cooldowns).
... and the Volus as mentioned previously. Unlike other biotics which work well together the Volus teams up with anything; you can't prime effectively (Stasis alone) but you can detonate everything - Overload, Warp, incendiary ammo, Incinerate, Reave ... and so on. Also has a decent anti-boss debuff and can keep the team standing with a well-timed shield boost even on some of the dodgy upload missions (lockout bug notwithstanding).
