For me it's a number of things. Durability and peace of mind is one, but I'm lucky to have a few guitars and to have only ever had to do a refret once so it's not really the main one. Your point on buying used is good too. I definitely have less concerns buying a guitar with stainless steel frets. The main thing though is really the glassy smooth feel which never gets in the way of expression on bends and vibratos. I love PRS, but they're among the guitars I play kinda less, and it's a small detail but a good part of that is due to the fret feel. And that's with PRS actually being among the best in non-stainless. Now this is subjective and I'm sure there are people who actually prefer a bit of friction, but for me that's the reason if I had to pick one. As far as objective things go, I do find I have less string wear and breakage with stainless (I attribute that to no rust buildup at all and no small invisible wear on the frets that wear down the strings). Re: the note on 2020, it's a matter of people's perceptions changing and more availability. A few years ago people were still using SS frets as an argument against some brands ("stop talking about how your stainless steel frets are great, my Ibanez with REAL frets is a much better guitar"), there were still a lot of cliches ("luthiers say it's bad", "stainless steel frets don't even sound good" etc), and it was hard to get a hold of them. Now that it's common practice to see them on the high end stuff all around (TA/Suhr, Aristides, EBMM, even Ibanez starting to put them on the very high end...) people are starting to see there's no downside for the player, and we're seeing more availability too as a result. So it can become a make or break because the choice is there. Today if I have to chose between a Schecter Elite with stainless steel frets and a Jackson import without, this will weigh heavily in the balance if I'm going to feel the difference every time on every bend. Couple of years back it wouldn't have been a make or break in some cases, but just a break or break because there was no option (I mean...except Carvin, but people are going to say again that I'm too big of a fanboi so..).
