It certainly works, however in my very limited experiecne, it's slightly
more tricky to use than Hypre as we've found that it requires a few more
options.  Gamg is very flexible and part of PETSc so it ties in nicely.

I'm not sure if I'm missing something with this question.  I don't see why
this preconditioner would care about the mesh structure, it's abstracted
well above that level.  From libMesh's perspective, it's just another
preconditioner.
