I do not care for them. Just too small. I can kinda handle them if they’re on something with a flatter radius. Like the Clapton. It has vintage frets and a 9.5” radius. I can handle that, if I *have* to. Thankfully I don’t have to. Likewise, I can kinda handle a 7.25” radius. If it’s got large frets. The combination of vintage frets and radius is generally speaking, positively useless. For me.
For finished maple fretboards I prefer very large frets. For rosewood I can go narrow tall, medium jumbo, jumbo, really doesn’t matter as long as they have enough height.
I have also never understood the complaints about pulling the guitar out of tune with large frets. I’m seriously heavy handed. Like, angry ape heavy handed. My main guitar has jumbos. It has been my main guitar for a little over two and half years. By this time next year, it’s going to need a full re-fret. I’ll be going stainless. That’s how heavy handed I am. I don’t pull it out of tune.
I’ve often wondered if these guitars aren’t instead being pushed out of tune? Like your fingers aren’t dragging on the board, or touching it for stability, so you’re accidentally slightly bending the strings across the frets and not realizing it? Because even as heavy handed as I am, I cannot push down hard enough on 10 gauge strings to put the guitar noticeably out of tune while playing a song. I can do it if I really concentrate on one note. But it’s definitely not something that occurs easily.
All that said, we should all play whatever we like. Screw looks, and screw arbitrary rules made up by a lot of people who probably don’t make their living playing music anyway.
Play what feels the best. And learn to love it for that reason. If that’s vintage, great. If that’s modern, that’s great too. But always keep in mind that “tradition” is mostly just peer pressure from old people.
