i use a merc stealth myself and i am very glad with it i like that i can have all the button around my one hand and the bigger w.a.s.d buttons do feel nice but does it give me a edge ?.
i don't know i think i could still be just as good with a standard keyboard.
the only thing i know that my mouse does give me an edge over a normal mouse and that's all.
as i see it if you are doing better with a gamekeyboard then yes it gives and edge over a normal keyboard if you are doing just fine with a regular keyboard then a gaming keyboard is obsolete and a waste of money
