Eeyore and Wildcard are hitting a good point with GBBRs. Because they're relative newcomers (gas-in-mag, open chamber systems - we all know classic airsoft were HPA blowbacks), the major hurdle in regards to improving and maintaining reliability and competitive performance is community knowledge of the particular system/brand you choose to buy.

In some circles, that may make WA/G&P or KJW the prime candidate, but on ASC we appear to have quite a large number of WE open and closed chamber users, as indicated by the encyclopedic threads on the two systems. This makes it a lot easier to diagnose and solve problems with the gun, and in my opinion put it ahead of other brands as an option for a GBBR, hence my purchasing one. If you go WE open chamber and run propane, there will be no shortage of info on how to get it running well enough to game against AEG wielding players, and in that respect KJW and WA would be close behind. The KWA system looks promising though, but time will tell. The brand itself also has its own forum, so that should help for finding information on upgrading the gun.
