Turing proved that the only difference between any two computers is how easy they are to program and how fast they run. All computers are functionality equivalent in that every computer that can be made can solve all the same problems as any other computer which has ever (or can ever) be made. So, in that sense, yes. VMS was more elegant than Unix because its design, syntax, and documentation made it easier and faster for users to grok and complete their tasks. As far as how fast or well the programs run, that's all about implementation details.
