I’m still early in my training but the sport pilot license just doesn’t seem like enough time to me. I’m usually a fast learner but I really don’t feel I’ll be safe after I hit 20 hours!
So it may cost you more or take you longer. If you are truly interested, you keep with it, or decide to stop.
However, if you do a bunch of research it may be right for you even though it usually isn't for anybody else.
For example, if I was a CFI and had a partner who flew with me, and who wanted a rating and refused to spend serious money, I might tell them to do a Sport and endorse it. But from this example you can see how super-narrow the use cases can be.
Or if you own a Japanese flight school in Hawaii, and get 20 candidates per month who are doing hobby-only flying, then maybe that business model works for everybody. (This is based on a real situation. PPLs were granted to students who could not speak English on the radio, so the FAA stopped that.)
