Even in small sizes like an 80mm .. I’d question what this really does vs say a 90mm mak, or a 100mm f/5 newtonian well made.

The only issue with that is that there are also a lot of junk Newtonians out there that give the design a poor reputation.

And yes I do own two small refractors - a nice 70mm quad APO and a 70mm f/10 achro for my son which I regard as disposable if he breaks it. But a 90mm mak will slay these two.

/me dons flameproof suit....
My dilemma too Wavy is getting a big and excellent 140 plus with great glass ..though prob Doublet fpl53.. better contrast (less glass).Or just look through my other scopes.

Will wait and see what SW comes out with.... VIZ 150MM ED Apo ; it may be very good for visual, doubles etc..
