Technically, the 540's would be one step up. A "little" lighter, different spindle, and can be installed only with an 8 mm allen. I am also convinced that the 540's are made with superior bearings and will last longer (I don't have actual "evidence", but hey, this is BikeForums where opinion and anecdote rules).
Depends if you are a Shimano or Cranky Bros kinda person. One useful feature of the Shimano's is adjustable release tension. The rest of the discussion is like Ford vs. Chevy and I'm not going there.
Here are the 520's I will be installing on one of my other bikes soon:
