Okay, I just spent the last thirty minutes studying Ben 10: Omniverse episodes, and here's my conclusion:

Humungousaur is the most used alien in the series, with 12 transformations.

Feedback is in second place with 11 transformations.

XLR8 is in third place with 10 transformations.

If you don't believe me, see for yourself here on the wiki or on the list on my blog. Also, I want to point out that I'm counting all of 11-year-old Ben's transformations and Ben 23's transformations.
