In my experience, I wouldn’t recommend it.
I have one on my Thorn Raven Commuter/Utility bike but as long as its dry I’d generally ride something else, for commuting usually my Genesis Fortitude with an eight speed Alfine hub.
The Rholoff hub itself is well worn in, having been in 3 different frames. I find it is noisy and draggy in some gears. They are also expensive as an initial outlay, but you would probably recoup this in the long run. Mine has had regular oil changes and a new sprocket and is on its second rim.
The major advantages for me are minimal maintenance and the ability to change gear whilst stationary, the ability to change through multiple gears with a simple twist of the shifter and the shear rugged dependability of the hub unit itself.
There is lots of information on the hub on the SJSC site.
