Idaho,
Well, consider this: You can buy a rusted out POS SUper Cub for ONLY $50 or 60 K. Then you can put another $50K in it, and you've still got less money in it than you'd have in a NEW Scout or Husky, course the airplane will be worth less than you have in it, just like a new airplane would.
As to people switching, some are. Note that there are VERY few Super Cubs operating under 135 certificates in Alaska these days. Can't make any money with them, or with Scouts, for that matter, but there are a few. Guides still use them(Cubs), cause they can trash em and buy another beater the next day. That said, I can show you Scouts being used in both roles, working hard, and keeping right up with the Cub guys, every day.
The Super Cub has a wealth of parts available from a number of vendors. There's no doubt that this is a big advantage to a commercial operator, and to a lesser degree to a private owner, both in cost of operation and in keeping it running. Can't argue that one.
As to me, I flew Cubs AT WORK for a number years and thousands of hours, and CHOSE to switch to a Husky. Three Husky's later, I'd do the same thing again. The Scout didn't fit my profile (though I'd have loved to have had that heater) for my work, and NEITHER did the Cub for the area that I had moved to and the work I was doing.
The Husky, with a PILOT, will go pretty much anywhere a Cub will on wheels, but on floats and skis, it will go places NO Cub can come out of. It's twenty miles per hour faster than most Cubs, burning over a gallon an hour less fuel than the Cub at the same time. It will work at high density altitudes better than the Cub as well. A friend frequently lands his at 15,000 feet.
So, my choice wouldn't (and more to the point WASN'T) the Scout, either, though I flew one (and a Maule M-7) while I was deciding what worked for my projects. The Husky did it for me best, and for several thousand more hours.
That doesn't mean the Scout is not as good an airplane as the others, just that it didn't fit MY work profile.
There is also the "Super Cub Aura" to consider. We hear this all the time. Frankly, I give a crap less what you fly, as long as YOU are happy with it.
I also been flying little airplanes at work long enough to know for a fact that 99% of making an airplane work is the pilot, NOT the airplane.
I've had very experienced Cub pilots (working pilots) tell me in amazement the places they've seen my Cessna 170, and that they wouldn't land there in a Cub. That was the guy who owned it before me. He was pretty much a superb pilot, I'm told, though I never flew with him. And, believe me, when these cub guys I'm talking about say stuff like that, they aren't trying to make me feel good about my airplane. Just shaking their heads in wonder..
In the end, whatever winds your watch is fine with me.
Just don't degrade someone else's airplane simply because it wouldn't be YOUR choice.
Adolph Galland, the fighter commander of the Luftwaffe during WW II was asked years later which of the many aircraft he'd flown during his long flying career was his favorite. His answer: "The one I was flying at the time".
That works for me..
