Given that he didn't use the Ultimates very often, and that he only used a total of 8 out of over 40 of his base aliens, yes. And he did.

I doubt Kevin would have been that powerful were it not for the Ultimatrix energy he absorbed, so without the Ultimatrix, Ben wouldn't have needed to access an Ultimate form to defeat Kevin.

Ultimate Swampfire didn't exactly defeat those stone monsters, just hold them off (and not by himself) until Baz- El gave the orb back.

Vilgax was already defeated by Diamondhead earlier in the season. Ben obviously didn;t need an Ultimate there.
