I bought an El Mar SS (the nice white one) last winter and haven't used my full sus since. The reason I chose the El Mar was adaptability - geared, singlespeed, QR or 142x12 rear, 15mm rigid steel fork, tapered head tube and big rear tyre clearance. This all meant I could swap bits between my bikes easily. At the time the only comparable frame was the Niner Sir 9, and my demo ride didn't amaze me as much as the Salsa.
I have ridden it rigid SS all winter, rigid geared and geared with front suspension. At the moment I have settled on rigid geared (1x10) for the summer. I much prefer the handling with the rigid forks to my Rebas (not sure if they are stiffer or just a different offset but the front tracks way better) and it hasn't got tiresome yet - even on longer rides like Dyfi.
I can't compare it to the Inbred though!
