Tournament play definitely has an upside. I was recently very involved in the tournament scene. As mentioned it is expensive. Guns are typically more expensive and you go through paint more quickly. I'd say go for it if you can afford it. I played in the world cup as well as a local series and had a blast, but teams are hard to keep together in the long run unless you have some financial help (sponsors). I now prefer more of the woodsball scene as it is not only cheaper but still gives me an adrenaline rush, and for me money is the issue.
