In terms of physical strength, no. Otherwise yeah I could see it. Besides the obvious being Alien X and the fact we saw Ben defeat Gwen in Absolute Power, the fandom states Ben is good at freestyle hand to hand combat. Even though Gwen is a trained black belt, she had help from Ben who would know a few of her moves.

In terms of feats performed, completed has the others beat with the big bang. If the same quality of failsafe is present in others, then the ultimatrix is the most powerful. The Ultimatrix is extremely glitchy on other parts tho. Yep, that's a definite downside on it's part.

Alien X is, by far, the most powerful alien in the Omnitrix. He can warp reality to any extent he desires, but only if Serena, Bellicus, and Ben can agree.

Due to him being 295 feet tall (90 meters), Way Big can often easily overpower his opponents because he packs enough power to beat an entire army. His size also grants him incredible strength and speed. Way Big has also shown great durability, withstanding fire from enemies while barely even feeling them.
