I do enjoy SS frets, although it's certainly a nice to have, but not a deal breaker. Mainly for the smoothness and nice shiny look. My 18 year old RG570 doesn't have any notable fret wear and it must be my most played/gigged instrument. My Dingwall bass though... fucking hammered those frets, the fret size and playing style are likely the cause though. I've had that about three years and a couple of frets have definitely sustained some decent wear in that time. Personally I think XJ frets will last ages if treated well no matter the material.
