Sure the Krylov has better accuracy... but according to some random sketchy website that I googled the "general" damage of the voss is 25 and the krylov is 27... and it also gives this info..
.................................................. ....Voss / Krylov
Shots to Kill Infantry (Head)...................2...........2
Shots to Kill Infantry (Light Torso)...........4...........4
Shots to Kill Infantry (Heavy Torso).........5...........5
Shots to Kill Infantry (Extremities)...........8...........8

So unless you are engaging someone who is wounded in the small range where the krylov 2 extra damage will make a difference the whole damage argument seems kinda fruitless (I know I'm oversimplifying this, crazy math person feel free to rip me apart with some extremity/light torso combination - but come on, most the time the extra krylov won't save yours and end his).

The accuracy of the krylov is significantly better, but you get 10 more chances to make a quality hit, or 2 or 3 more chances to line up the crosshairs and take a quick burst at that unsuspecting guy running in the near distance. Not to mention the advantage of the extra 10 rounds when facing multiple enemies (such as on the TG server where very few roam alone). In my opinion the accuracy advantage would best be shown when shooting at a sedentary target when you have time to line up a good shot, but in the heat of the battle I don't find myself patiently aiming, I figure the guns guess is as good as mine (if the target doesn't move I'm switching to rockets anyhow).

I don't see how the krylov can be considered definitively better than the voss. They are at least about equal in effectiveness depending on how you chose to use them. But since the krylov sounds fruity when you fire it, the voss is the sure choice.

P.S. I just looked at a sample of 5 people who posted in this thread boasting krylov superiority, however all of their accuracies were higher with the voss.
