I believe you are using bad terminology. ‘Quantum gravity’ refers to any attempt to reconcile quantum mechanics and general relativity, and string theory is one such theory (as well as a theory of everything). Perhaps you are referring to loop quantum gravity, or more broadly, to any theory of quantum gravity other than string theory?
Perhaps I should have meant loop quantum gravity. I confess that I am speaking beyond my depth, and was just trying to give an example of a central dispute in current theoretical physics. That is the type of case where I would not like to lean heavily on my own perspective.
A minor quibble.
