I think for the casual aircraft owner who doesn't own the property that he/she is planning to land at, helicopters have many limitations compared to their utility. It takes a fair amount of effort to work out landing at places that are not airports. For a specific use case, it's great, but for the typical GA mission, it's slower, magnitudes more expensive, with only limited benefits.
From a career perspective, I like the blue collar, low and slow aspect of rotorcraft work. Even the upper escutcheons of the industry you're low and slow, and for the exception of 135 passenger charter work, not too much shirt & tie non-sense. That said, salaries do seems to top out much sooner than fixed wing jobs, with less job security.
The other problem is Uncle Sam produces more helicopter pilots than the civilian rotorcraft industry will ever need. At the FAA it seems we have tons of former military helicopter pilots in all sorts of varying jobs.I guess a nice government job with credit for prior military service is pretty enticing over flying rig workers in the Gulf.
