Neither. None of the console versions are mod-able.
But, if you must restrict yourself. Both are good, and both, have their weak points.
I have a PS2 myself, but won't bother with any form of sims on it, because they are not mod-friendly. BORING.

Two other options.
Witch Doctor way, get brochure from all game units, light fire.
Buy unit that makes prettiest flames from brochure fire.
Logical way.
Pick the one that gives you the widest range of options, at the best price.
