Not really...the Nexus is to Alfine what Sora is to 105. I think Alfine was also the only model rated by Shimano for XC use.
There was the curious Nexus Red Band which seemed to have the same internals as an alfine hub but no disc mount and could be respaced to 126mm.
+1 to the bar end shifter and V brake levers. Personally I'd avoid the integrated shifters - I've never used them in anger but having copped a feel in Evans they felt...bad. The standard alfine trigger shifter was great though.
AFAIK the only difference now between the Nexus and Alfine is that you can mount disc brakes with the Alfine. All the Nexus versions available online are the 'red band' version (SG-8R36).
