With PS2 you can play ps2 and psx games. It has a good game base already so you can buy games that you'll like now.
Xbox is newer and the games are good. However, the games will get better. It's a new system. The games always get better.
I got a gamecube recently. I like Nintendo and it was $50 cheaper.
Seems to be your choice.

What is it they say about silence being golden?
