if you want something with a consistent FPS you should get the TM, but its hard to compare since one is AEG one is GBBR,both have their pros and cons, aeg's are more consistent and reliable with more upgradable parts, since its a TM, the only thing the WE has is the blowback function that creates the realistic feel to it, id suggest you stick with the TM m14, and just get a mosfet system so you can have insane trigger response
