Anyone playing on UB or full tilt?

[Madjohnny]

Not sure where to post this, but basically I'm thinking of moving off partypoker and setting up either on UB or full tilt poker.

I play $25 & $50 NL.
Just had a couple questions:

1. Which site generally has more games running in those limits?

2. How many tables can you play at the same time?

3. Are the 25 or 50nl games pretty tight or are fair number of fish?

Please share your experience with either of those sites if you have played there.
