Ice is offensively better if you aren't going to have a diverse attack set. It hits everything - there isn't an ice absorbing passive (Like Flash Fire, Water Absorb). Also, it's strong against flying, which is a very common dual type.
Oh, any item/TM you are dying to get a hold of?
I'm legendary at the game corner, so psychic/thunderbolt/ice beam/flamethrower are pretty easy to make togepi hold. As is wide lens/zoom lens etc.
