I am probably in the minority
1. Geth- easiest by far, NO SYNC KILLS, never a problem for me
2. Collectors- next easiest, once you've played them a few times they are not bad
3. Cerberus- I have the worst luck w/phantoms hiding around corners and sync killing me
4. Reapers- toughest, the Banshee wailing always seems to distract me
Sorry, but I had to lol. This is exactly the opposite for me.

The only thing about the Reapers that really give me trouble is when I'm fighting a Brute and suddenly I'm grabbed from behind by a Husk, giving the Brute enough time to charge and kill me.
Cerberus is fine, as well. Pretty much just the Phantoms that I avoid like the plague, unless I'm playing my N7 Shadow. Then I go hunting.

The Collectors, as has been mentioned are the trickiest on bronze, but I don't find them as bad on other difficulties as some of the other factions are.
The Geth are easily the worst for me. Hunters constantly sneaking up on me, Pyros stripping my shields, and now the bombers occasionally coming out of nowhere and obliterating me because I'm caught in Prime/Hunter induced stunlock. Yeah, they're easily the ones I find the most difficult.
I don't think you're in the minority, though. I've heard plenty of people in-game complaining about how much harder the Collectors are.
