Rex might be the most powerful in some situations. If his Nanites evolved to a point where they could assimilate the technology of the Omnitrix, he could gain all of Ben's alien powers and then some. His ability to rapidly adapt and create new constructs with his Nanites gives him a lot of flexibility in combat and problem - solving. Also, he has more experience dealing with technology - based threats compared to Ben.
It could be Ben when he transforms into Alien X. Alien X has near - omnipotent powers. He can manipulate reality on a cosmic scale. In a crossover, he could potentially use those powers to control the Nanites or even restructure Rex's powers in some way. However, he's also very difficult to control, so it's a double - edged sword.
Actually, it could be a combination of Ben and Rex. If they were to somehow merge their powers, either through some kind of accident or a new invention, they could create a being with the best of both worlds. This new entity would have Ben's alien forms and Rex's Nanite control, and could be extremely powerful. It would have the brute strength and unique abilities of Ben's aliens, along with Rex's ability to heal and create various tools and weapons with his Nanites.
