I would like to know which are the best poker rooms

Regards

I think there are many topics made about this question, try to find them, or someone will give you a link...

Pokerstars, Ipoker, Full Tilt...etc, etc...

Stability, Fairness, and the most members = Pokerstars

Fun, lots of pros, great security.... = Full Tilt.

Me I play on tilt.

Pokerstars is the biggest, and there's always a good tourney going -- or 15. Always plenty of cash tables at all levels. They have fun games like Badugi, 2-7 games, 8 game. Puts on poker series, with money guaranteed, and lots of guaranteed tourneys.

That said, I mostly play at Full Tilt, because I feel comfortable there and have lots of poker friends there. Also tons of tourneys, lots of action. Also has special poker series. Pros are highlighted and sometimes play at small stakes tables for fun, and in smaller stakes tourneys. Bust a pro, get a T-shirt. They also have the FT Poker Academy, with lessons, sessions and such to help you improve. Love that.

Bodog is fun, and has pretty soft freerolls. Not nearly as many players, so it's hard to get some games going.

I like limit holdem SNGs, and am more likely to be able to play at Full Tilt -- and i know most of the regulars at my level and have notes on them.

I don't play at Ultimatebet nor Absolute Poker hardly ever anymore. I don't trust them.

I'm in the US, so I have fewer choices than those who are based elsewhere. I hear Party Poker is still going...

Stars and FT certainly have a huge share of the market, and for very good reason.
However, when you realise that you can play on a different site and be getting 50% of you rake returned to you each month it's hard to keep making a case for the top 2 if you're a serious player.
Even if you're in the US

In LA the biggest room is the Commerce and arguably the best.

Best rooms in Vegas are Bilagio and Venation. Although I like the MGM better for a bit softer game.

As for online .. other people have already talked about it.

for me the best poker room is usually the closest one to me, which is currently 2.5 hours away =(
