I have used PVA. The problem with PVA is its hard to fix mistakes. Any runny spots, or a bubble, or a piece of dust that lands on it is there for good. I like waxes because I can buff out any mistakes.
For sure, a polished wax surface will give a slightly better finish, depending on how nicely you apply the PVA. Some guys use a spray gun which apparently gives great results.
I have however had issues with the piece taking bits of the gel coat with it when releasing, even after 6 layers of wax on/off. Maybe it's a bigger problem when you do a high temp cure, I dunno.
But I'm happy to live with tiny swirl marks from the PVA if it means a problem-free release, especially with a green mould (first time use).

Has anyone tried Loctite Frekote release agents?

I've used Smooth-On Ease Release in the past but didn't like it. I found it too slippery for hand layup as the wetted fabric moves around very easily and doesn't cling to vertical areas and slides down.
