I have had a HP for awhile, so here's my thoughts on the good points and the nitpicky bad points. You have obviously shot it enough to know the good points but perhaps not enough to see any problems, so I'll go into more detail there.
Good - single action, thumb safety, near perfect ergonomics, natural pointability, reliable, readily available 13rd hi-caps
Bad - magazine disconnect, long trigger reset, the beavertail, a couple of sharp edges, hammer bite
The magazine disconnect is a pain when at a competition, clearing the pistol for storage, etc. It should be removed ASAP and its removal will clean up the trigger pull slightly. The trigger reset can be shortened if you have custom work done. There are two points on the beavertail area of the pistol that will wear a little skin off over a multi-day pistol course. The safety notches in the slide have a sharp point that will catch you occasionally when racking the slide. Supposedly a few people get hammer bite, but this has never happened to me or anyone I know.
The other "bad" point is that it becomes your standard when evaluating other pistols.
