This system or 360? (this i on other board too)

I'm going to save up every cent to get a new system. I want a PS3 and a 360. Now I like them both so much I want them. Assuming my dad lets me buy one (Probobly not, no promices) which should I get? They have basiclly same games. Here are the 3 game I want when buying (How much do these cost by the way)

1.)Call of Duty 4

2.)Rainbow six Vegas 2

3.)Assasin's Creed

My dad might not let me get 1 or 2 for M rating. Games subjest to change.
