The "strongest character possible" thing, when taken to its logical conclusion, is ultimately just going to be an Omnipotence paradox. An Omnipotent character must be able to make an object so heavy they cannot lift it, but if they cannot lift the object, then they by definition are not Omnipotent.

The concept of a single true "strongest" character doesn't work because someone else can always come up with a conceptually stronger character by saying their character has your character's power but even more so (in theory, that is; ultimately, the "cap" for any character's power is going to be infinity no matter what).

In essence, Ben has some of the most potential of any character in fiction because of all the different forms he can take, but he's definitely not the "strongest" in any traditional terms. Strength isn't a good measuring stick for a character's potential to win a fight unless you're in an extremely basic DBZ-esque universe that works solely based on power levels.
