My main player guitars these days are carbon fiber and they all have mirror polished SS frets. But as I said before, there are plenty of nickel silver fretted guitars at my house and in my past. They've had countless hours of play time and show minimal divots or wear."Stainless steel" is a semi-generic name for literally dozens of alloys. Some are even non-magnetic, which is weird for steel. As I recall from my materials science classes back in engineering school many moons ago, there is a whole range of metallurgical properties under the "stainless" umbrella.
Purely anecdotal, but I got a first-run AD27 last July. Neck angle and everything was great, no big set-up issues. By September I had it in the shop for fretwear. Guitars I've had and played hard for many years didn't have frets anywhere near as bad as how these looked. There was even a bunch of metal "dust" coating the fretboard around the areas of the wear. It was real strange. I took it to Third Coast, an authorized Taylor shop here in Chicagoland, they didn't understand it either. Taylor doesn't normally cover fretwear, but they made an exception and paid for the fret dressing.Since then there is a bit of visible wear, nothing like what it was. But I've also been playing it far less often, so who knows.
