I fly with it and I don't have much problem killing people 
I'm willing to bet that the majority of your deaths in fighters can be attributed to the fact that you aren't able to push your plane to the limits like the person that shot you down did because they didn't have their hands tied.
Unless you're learning how to play and fly, there is really no reason why to have stall limiter on. It only hinders the player with it enabled and gives the player you're fighting against that has it disabled an advantage over you, one that could be the determining factor on whether or not you win or lose the fight. Sure, against players that aren't as good as you are, it really might not be that much of an issue. However, it still does not change the fact that you're still at a disadvantage and it's one that you have to over come and why make the fight harder for yourself for no reason?
