I like playing a lot of various games. Keeps things interesting. If you are going to play games like Limit Omaha H/L it is more important to have a rakeback account. Reason being that you will end up paying quite a bit of rake, but profits will be cut in half many times because of the H/L factor. This is always more apparent with limit since you can't get quite as much money in the pots.

It can be difficult to find decent traffic on alternative games. Omaha seems to have the most traffic of the non texas holdem games. Stud sometimes can have traffic, but usually in the pot limit format. On FT I loved playing FL Stud, it was awesome and easy to beat.
