Cutting right down to the chase...for a function over form, but with nice stuff too kind of person.
If you buy an AEG....then touch/shoot a PTW...IF the PTW is reliable and works...you will never touch the AEG again.
BUT you will always want that safety blanket of the AEG when you take the PTW to a game.
*the other caveat being if you want some other style or weapon (i.e. SAW, AK, etc...)...then you'll end up with a half dozen rifles anyway
