I don't know that the impedance issue is all that significant, at 
least at HF.  Weatherproofing would be why I'd choose N over UHF 
connectors.  Cost (and the fact that most ham gear has them) would be 
why to choose UHF over N.

In theory, UHF connectors carry more power than N (the center 
conductor has more contact area, etc.) but since either one will 
carry more than 1500W, it be a non-issue.

When the connector was invented (back in the 30s?) 30 MHz was ultra 
high frequency.
