I love mine, but a newer three channel (or roadster or road king) is more versatile. I think the raw tone is better on the rackmount though. You'll get a lot of differing opinions though.
I loved my recto in the past, but now I'm thinking of all rack gear. I just don't want to haul around a head and rack. I would rather have just a rack.
I've had three rackmounts, a very early dual recto (Sn was in the 200s) a roadking V1 and two roadsters.
There is some internet lore about the rackmounts, in my opinion they sound great, earlier the better and the oldest I can find is around my SN (8xx) and rev F. I had a dual recto head that was SN in the 200s back around '94 (chrome chassis and leather, I'd kill to have it again) and it was awesome, but there is enough of a gap timewise that I can't say if it sounded better or not. Both amps sounded great. The big issue with either is that you give up a LOT of useful features that they added to the newer heads - like a solo level that was footswitchable, a third channel, etc.
I had a weird rack rig that I was going to use until I tried to lift the damned thing that included a rackmount recto, a mesa quad, gmajor and a gcx switcher. It was like the six channel all tube mesa from hell - had four channels from the mark series with the quad going into the power section of the ractifier and then the red and orange grind from the rackto. It was an interesting idea for sure.
