I had both. I started out with the vinyl sent the seat back for bad stitching and paid to have it upgraded to leather looked much better .It moved my A$$ back about an inch which turned out to be uncomfortible for me so I sold the seat here.I personally like leather better than vinyl I think it feels better.
I have the leather Profiler and love it. I think it looks and feels much better than the vinyl. As with anything it takes a little care to keep it looking nice. I use mink oil on mine about once a month. Most any good leather conditioner will work.
