Like I say though, it's a completely different skillset. I agree that CQB needs a more aggressive approach and woodland can reward a more tactical style but I would say that the speedsoft side is a different thing entirely again. A good speedsoft player wouldn't do very well at Longmoor just the same as someone that only ever plays in the woods will struggle at The Mall.
Yes, the kit is different but an M4 (say what you like about them) will work in all those scenarios outside of specialist roles (and to be honest a well set up AEG isn't going to be at that much of a range disadvantage out in the woods).
The thing is, if you drop down from the upper levels of the people that deliberately specialise in one form of play (speedsoft/sniper etc) then in terms of being good rather than exceptional, it is no more difficult to play CQB than it is woodland, you just need to employ a different approach. In MY experience people think that one or the other is more demanding than the other purely based on how much time they've spent doing one over the others. People that play a lot of CQB think they're better airsofters than the woodland lot and vice versa. They're both (usually) wrong because all they've done is improve one skillset at the cost of the other thus THEY find the one they don't usually do to be more challenging - the fat knackers that wander about like a tit in a trance at The Mall think woodland is better because that's what they can cope with and the kiddies that tear arse about on a woodland field complaining about nobody taking their hits from their uber leet high cycle MP7 while getting sniped from the other side of the field think that that CQB is better because they have three parts of f*ck all situational awareness beyond 3 metres.
It's entirely possible to do well enough to enjoy yourself (which at the end of the day is all that ACTUALLY counts) by being slow in CQB or running about like a loon in woodland BUT it's no more difficult to do either.
