Field games are nice, CQB is too but the best is if you get both at the same time. A couple of buildings, river or a lake and some field and woods its perfect.
CQB by far is the best. The adrenaline rush you get when ure clearing rooms and you're hand eye coordination is tested. Plus im the military so It keeps my skills where they need to be to do the real thing. And when we play all we have is eye pro, shorts and a shirt. Try that wit 370FPS and up weaopons at close range.
I guess a mix will be my thing... haven't got a chance to try that kind of game tho... so far I prefer field game. it gave me a much steadier pace of adrenaline... CQB game is a tad too fast for me...
I would think a combo of both would be ideal. We dont have a cqb facility around here but it would be great to add some cqb structures to the outdoor field we use.
