Personally, I don't use mounts - I don't like the bulk and the look of them.
Of course, I avoid MNH when possible, and if it's unavoidable (generally the case for pretty cheap, plentiful material), then I hinge it anyway. No qualms doing so.
For my Scott International, I exclusively use hinges, although perhaps I would be tempted for anything ultra rare (here I'm thinking Syria 106c, which I have in an envelope, but not put into the album yet).
As for the vintage hinge mania - yes, they're better than the current ones, but not so much better that they're worth the astronomical prices they fetch on
ebay.
My trick is to use modern hinges, but cut in half, and then stick the longer part on the stamp, and the shorter part on the album page.
The opposite of standard practice, but should I have to remove the stamp later, it means less wear and tear on the album page (which is itself vintage). Then I float the stamp in water for a few seconds and the hinge pops off perfectly. A quick press and it's good as used!
