I've pasted my stealth vs armor kills, deaths, KDR, KPM and ranking so you guys can have some (admittedly empirical) evidence of how strong armor is vs stealth.

You'll note that I have 7712 stealth kills; the second ranked player on PC has 3766: http://crysis3s.com/leaderboard/pc_smode.stealth#start_0_GruntPyre

Stealth, while fun in this game, and a huge part of my playstyle for matches (as I tend to play as more of a disruptor, counter-sniper and ambusher in all game types), is simply not as efficient as toggling on armor, or rolling with auto-armor for pure kills.

My recommendation, if you want to improve your Kills/Deaths Ratio, is to only ever use stealth to get the jump on someone OR for reloads. In basically every other scenario armor or auto-armor is better.

*Assuming you are sniping or using a bow, obviously you want to be in stealth mostly.
