Definitely Kevin 11,000. While Ultimate Kevin is more badass, it doesn't mean that he is more powerful. Like Darth Vader compared with Rogue One and the Original Trilogy. Kevin 11,000 shows more control over his mutation better than Ultimate Kevin and we didn't see a lot of Kevin 11,000's powers because he was kicking Ben 10,000's but except when he transformed into Way Big. Even then, not even a scratch on Kevin. Meanwhile, Ultimate Kevin got beaten with a Sonic Doom.
