I tend to agree with you Shakaru. Pretty accurate asessment. I have yet to have any issues on CampBX, but I use them the least between Tradehill and MTGox, so I don't know how their support is... TradeHill is, in my experience, a little slow in support issues, but not to the point of complete ridiculousness like MTGox, thankfully.
I don't think I've had a Gox problem actually addressed properly, but dealing with Tradehill has been much easier and they have even contacted me about things before I raised a problem. The Intersango site works well, but I don't have much there so limited experience. I've had a lot of fun over on "World Bitcoin Exchange" playing with AUD and haven't had any problems there - I like their statement generator. Other exchanges have been good and bad, and some are gone.
CryptoExchange put me off because I couldn't find out enough from their pages (like fees and transfer methods) so didn't follow up.
I need to read more into CampBx because of the positive press. (but being outside US, I'm restricted to wire transfers and unless I'm doing big-ish transactions, the banking fees are pretty terrible).
