I like the Sturmey b/c you have freewheel, coaster, or drum options. And, typically, a smaller OLD, so you won't need to spread your frame as much to fit it. But, it seems like QC from Sturmey-Archer is a bit off nowadays. Some ppl get solid hubs; others have some nightmares. I built a wheel around an XRD3 for my wife, and there was something waaaaaay wrong with the guts. I ended up getting another one from the dealer, and swapping the guts between the shells. Bonus: I did get some decent spares out of the deal.
