I have tried both methods, and have found that soaking super-glue under the fret makes a good solid connection with the fretboard, thus avoiding dead sounding frets; however, I pity the poor fellow who attempts a refret down the road!

I had to deepen the slots on my FB yesterday. I chewed a few of them up in the process.

Not a disaster, but I will be running glue under each. Probably titebond, to make sure they STAY seated. I don't like using Superglue, it cures WAY too fast and wood glue is a lot thicker and better for this application I think. I gotta make my fret drill press caul today so I can press them in.

You can use a slightly taller fret as well. little more flexibility
For another example, when you make a barre chord on your guitar, you are simply moving the zero fret all around the fingerboard using your finger as a capo with the same size fret wire in every position. So it makes sense that a zero fret with the same size wire will work perfectly when set up correctly.
Best, Bob Shade
That example makes sense to me. Thanks Bob. And everyone else for their insights. Different stroke for different folks. As long as your method works for you, right? I will use the frets I have for
low action.
