Which version of Plants vs. Zombies is the best?

The xbox 360, ps3, and pc are all really the same version i personally enjoy playing it on my lap top because its faster just to aim and click with the mouse instead of switcher through lanes with a joy stick but i like all other games on the consoles so i would say pc but i would think that it would be complete on the iphone i was thinking about getting it on my iphone but then again they dont really make long games for the phone so i would say pc
