![The question owner (didn't really) accept this answer as the best at some point][1]

I'd like to add one more criterion to the conversation, so that a "high rep" user is anyone who:

1. Meets some expected rep score / percentile / ranking / etc.

1. Makes use of **all** their "powers", and does so correctly.  
(ie, doesn't just use the basic "low-level" "powers", but *actively* acts as a high rep user).
