I fly one because it's a better aircraft for the sort of flying I like to do, and because when I was in the market to buy it was, well, cheap.
I don't think makes me better at anything except takeoffs, landings, and ground handling. All the rest is just flying, same whatever sort of undercarriage the aircraft has. It is entirely possible to learn to fly properly in ANY aircraft, from opening the hangar doors to closing them at the end of the day. It is the student and instructor that matter, and their hard work and inability to accept "good enough".
I learned to fly on a C150, because that was cheapest. It cost me £28 per hour, at a time when I was earning £25 a week in my day job. If I had waited to be sure to have the money to continue after the licence i probably wouldn't have got my PPL. I had just enough saved to do the first 20 hours of my licence, which I completed in the then 40 hour minimum, spread over two years as I took on odd jobs here and there to pay the rest, borrowing the books and all home study. So, yes, often it was a struggle to keep flying, but I managed, and converted to a cub with ease. A fair bit of gliding kept me going post PPL, until my finances improved and I and my other half bought a cheap tatty cub. We've been flying it for thirty years now. It isn't tatty now. Apparently it's a collector's aeroplane.
Oh, yes, and we use it for touring. 75kts is fast enough to get there, eventually.
