for me classic NL is the best. in PKO is more gambling
That equals more fun right?
I like the opportunity of making money even though you do not finish in-the-money.
When the deck hits you - many persons are willing to risk, especially if you are short-stacked. The chances of a triple or quad-driple up are great.
Classic is fine but I like the improvements - like the Mystery Bounty - it is awesome!
