Favorite Poker Site?

[Yo'Maha]

As I rarely see many well-known players calling Paradise Poker thier home, I was wondering -

#1 - Why does it seem this way? Is there somehing I don't know about my poker home?

#2 - What is the best place to play online and for what reason?

I have been on Paradise Poker for a little over a year now but am curious if I should be broadening my horizons. I tried Ultimate Bet and didn't like the gameplay or the amount of tourneys offered. Any suggestions? Look forward to reading your replies. Thanks!
