If any of those theories worked, there indeed wouldn't be an issue. But none of them fully reconcile the massive discrepancies in predictions without adding glaring discrepancies of their own.
If by "the difficulties of quantum gravity today are mainly experimental" you mean that if we could go and study the behavior of quantum mechanics near the event horizon of a black hole we might have solved the problem already, you'd be right, but that's kind of tautological.
