I highly recommend playing live if you can, whether it's a cash game or a tournament. I played casino poker live for first time about 6 months ago, fell in love with it. Still play online, but live is where the money's at and it's just to me much more fun.
It plays much different than online so takes some adjustments for sure, I lost my first $1/2 live BI quite quickly! But if you can afford to try it, or you win an online MTT like I did that gave me the chance to take the shot, go for it! Make it a goal to try it!
