User blog comment:Kevinlevin13/WHO DINKS DAT ULTIMATE ALIEN IS A 'NOT AS GOOD SERIES' AS THE OTHER 2 BEN 10 SERIES/@comment-3317088-20110124181109

Depends...I am not a big fan of Ben 10, I like Ben 10 AF best but some Ben 10 UA episodes are great. Everyone has a diffrent taste so its hard to find one answer :)
