To me, frets are like shoes, everyone has different tastes. There are enough choices these days, you can install just about anything you like. I use 148s for my own basses, they feel good to me. That's as scientific as I get! I know some folks like to recreate the feel of frets from the past, but that's probably harder to do than one would think, especially if the particular fret wire isn't even made any longer. We just have to make do with modern frets!
