Personally, since I practice Wing Chun, I prefer tight spaces - not least because many fights I've seen take place in bars and alleys where space is limited. What Wing Chun does, it does very well.
Yet, I think Wing Chun has some key weaknesses versus other styles - particularly wrestling style arts since you're playing into that range. I've scrapped with some long bridge opponents in the open and found that it does leave you at a disadvantage, as it makes it harder to close down - each time you advance they can simply retreat a step to pop you back in the firing line.
Best thing you can do (short of taking up MMA or supplementing your style) is train against as many different fighters as possible.
