Unless you're a gun tech guru like Danke, I've seen to many WE's break, and their cold weather performance unreliable for any gaming environment.
As you know M4's are very modular, and any brand you can buy parts.
If you plan on never seeing any games, you can probably get away with the WE, if you plan on trying out some local CQB fields in the GTA area, you should consider the TM MWS or GHK M4s.
