ghosting is what happens when your keyboard can't register several keys pressed at once, i.e a,b,c,d,e all pressed at once. a lot of gamers press a lot of keys at once i.e strafe left with d, move forward with W, jump with space, and switch weapon with Q, and crouch with control all at the same time.
gaming keyboards are not less ergonomic, they're just a higher end product that can do more as far as keyboards are concerned, and as such also cost more.
all in all, what you should look for in a keyboard is pretty much how much you like typing on it, as that's the primary thing you do with a keyboard, believe it or not.
