Hollywood is great. Great reload bonuses and a very good player point system that allows you to buy more bonuses or trade them in for cash. Since I joined two months ago I haven't really played anywhere else.
As emmasdad said, the competition is soft and the table selection is pretty good.
I've done two of the $500 bonuses which clear at 12x. For me it's worked out to be about 80% rakeback. The 10x bonus on the HP site is only for $100, but if you go through bonuswhores.com I think you might have some other options.
Also, they have a $75-$75 refer-a-friend program, so if you signup you should get a referral from someone at BTP.
