The SRAM I-9 was faultless for nearly a year and 3k miles then it seized totally in January. Was returned, via my seller, then UK distributor, then Germany, repaired(under warranty) and made the same slow way back to me. Has been fine since, another 1k miles. By all accounts I was unlucky but I'm not happy with the SRAM policy of return to Germany. For this reason I wouldn't buy another and also the fact that I didn't need that many gears. Bear in mind it's a bike for commuting only, there is no commute i could possibly have, around here, that needs more than a 3 speed hub gear. I could easily do my 40 mile round trip in one gear and generally did it using 3/4 gears in the range max.
I came to the conclusion that a Sturmey Archer 3 speed, either AW or new SRF3(the latter is what I got) set up with a 2:1 ratio gave everything required for commuting. You get 3 gears approx 40, 54 and 72 gear inches, there's nothing around here I can't climb in 40 inches and 72 is fine as a top gear, I can hammer along at 18-19mph in that comfortably, that's approx 80-90 rpm. Plus I, and my LBS, can strip and maintain the SA hub, I can also afford to keep a spare wheel with one in.
I never tried Bollos Rohloff, but have tried others, they seem a great piece of kit but I can't justify the spend unless I was planning to tour. For general use the gearing is even more pointless than the SRAM, too many of the 14 gears would just never be needed. I still want one but, at present, it would only be in the 'Shiny Shiny' sense of wanting
Just my view and heavily bias towards the concept of a dedicated commuting bike, I have other bikes for other duties. If you want a bike for more uses then a bigger range hub gear may be a better fit. I also tend to ride in an old fashioned style, I change my tempo more readily than I change gears.
