I've got both and I've been playing the GameCube more, even after I bought GTA Vice City. Animal Crossing is just so addictive, and I can't explain why. That and SMS just seem like so much more pure fun compared to the darker PS2 stuff.
But I'm not disappointed with the PS2 - FFX, Dark Cloud, and the GTA games have been well worth it. (okay, maybe my assessment of PS2 has something to do with the game selection)
It's been said, but find the games that you want, then go with the system. Bottom line is that this is a GREAT time to be a gamer. Never have I had a better excuse for the constant sitting and snacking

I once thought that I would be upset at the lack of backward compatibility. It turns out that I don't play any of the PS2 games anymore. This became one of the reasons I did end up buying the PS3 (along with Blu-Ray and MGS4).
