^ I have the same opinion, that AF and UA started with pretty good stories. But then AF brought in Vilgax's kid brother and didn't explain some inconsistencies it had with the original. UA had a pretty cool idea with the Andromeda aliens, and an interesting premise with the Ultimatrix, but then Kevin became evil again, Ben suddenly wanted to kill him, and they didn't make any more Ultimate forms. Plus it had horrible filler.

The original is my favorite, with OV and AF taking turns at second place.
