KWA is the best of his guns, they tend to be for the hardcore gamer and KSC/KWA are about the same and also have parts abundant on many sites.
WE is okay but will eventually break. Good thing is it is TM compatible you can just gut and replace with aftermarket parts, except some models might not fit well with aftermarket parts. Small subtleties may occur in which you must file down certain parts.
KJW should be ranked last of his selection. From most of the reviews I was looking at there seems to be a common problem of them eatting themselves, meaning the metal parts start to shred and die. Which is the same problem as WE
