PC is the way to go. There is literally no downside (since the PC supports mouse/keyboard OR gamepad).
Also, once you tire of Oblivion (which for me didn't really take that long), get the GotY edition of Morrowind. It is superior to Oblivion in every way that matters, and can be modded to have near-equal graphics.
