Chop, no channel. But, I honestly think they look really good in any of the above combinations, you can't go wrong.
I have owned, chopped and channeled, channeled no chop, no channel and no chop and my current no channel and 2.5" chop. My fav is no channel and 2.5" chop. Least fav is Channeled/ no chop. Hardest to drive was my 6" channel and 4" chop.
