All of the GBBR's have their pros and cons. Of the makes you listed, (where most of my experience lies) WE has the lowest cost of entry, and can be made into a decent platform with a reasonable amount of work. I owned an original WE M4 (long gone) and a recent WE 416. I can say that there have been a lot of improvements since the guns came out.
You will need 5-6 mags, and, if you go WE, probably an RA-Tech NPAS and a Stinger hop-up. Realistically, you are looking at a start-up cost of at least $500 to get a mostly reliable, field ready gun.
At this point, my advice is to wait. KWA has their M4 GBB's at the ATF for approval, and upon approval (fingers crossed) their M4's with the NS2 system will warrant serious consideration. The catch is that you will probably need to spill at least $1000 to get a KWA GBB and sufficient mags to be competitive at most games.
If you can't wait, look at the KWA MP7. For around $500 you can get the GBB and 5 extra mags, and you won't need to do any upgrades on the gun. I'll shoot my MP7 over my WE 416 any day. It's lighter, easier to maneuver in the field, with nearly the range of the larger 416, and it's loud...everyone I've shot with mine has jumped when it goes off.
If KWA's NS2 M4 mags are as solid and reliable as their pistol mags, the greatest drawback to GBBR's, mag reliability issues, will likely be solved.
My 2 cents. That aside, you can't beat the G&P GBB's for external configuration options. If I hadn't heard constant complaints about the WA mags I would have at least 3 of the G&P GBB's.
