I didn't play much HU on UltimateBet, but the few times I did try to play, the traffic was really light even at lower limits, and the way UB takes keyboard focus away when it's your turn to act makes it a pain in the butt to multi-table if you ever type in bet numbers (which you probably should be doing most of the time).

FT's structure is faster, which is either a good thing or a bad thing, depending on your point of view. I really dislike FT's turbos, but FT's regular structure is very similar to PS's turbo structure for the first 15 minutes. I haven't played on PS, but from what I gather, the playerbase is much fishier at FT, but traffic is definitely low at the higher limits.
