Hmmm.

OS > OV, for what I consider better consistency in the tone of their episodes and quality of plot.

AF > UA, for actually selling the idea of an older, slightly darker Ben 10 series and not being bogged down by wildly confusing character development and horrific filler episodes (for a series which tried to sell itself as "darker and edgier").

Overall I'd rank it OS> OV= AF >>>>>>>>>>> UA :)
