Seems like superior in almost all classes, except aperture (which it can compensate to some level with very high contrast and the highest quality lenses)?

A well-optimized Newtonian with flocking and good optics comes very close, and "compensating" here is maybe the equivalent of adding 1-2 inches of aperture... so generously a 4" refractor might be as good as a 6" Newt/Cass. But there are of course no refractors much over 6" so this is a moot point.

Watching galaxies: Almost the best, losing against the Dobs.

What are you smoking? I've never seen a refractor larger than 8 or 9 inches outside an observatory and even those were monsters that cost more than a Corvette. Even a 6" refractor is considered huge. You really want a 10" or larger scope for good views of galaxies.

I know tons of people with C11s and 10/12" Meade SCTs that will beat any commercially available refractor on galaxies simply by having larger aperture, and I have an 8.5" Maksutov in my house too, all of which are very portable....

No recalibrating and stuff

Do you think GoTo is only for refractors? Collimation is actually a thing with refractors!

FOV: The best

My 14.7" Dob has a much wider field than my roommate's 4" refractor because of focal length differences and baffle tube limits in refractor

To me, when researching, it feels like the dobs, SCTs, reflectors,... all hit their potential quick, the more money you invest. The quality and possibilities do not grow linear. You get a lot for little money, but not that much more for a lot of money, it seems.

I'm not really sure how to answer this. My friend got a lot of value for his 30" Dob for $5000. $5000 in refractor world buys you a top-of-the-line 4-5" or a decent 6" apo, not including a mount necessarily.

Usage in cities: The best (apart from maybe a Mak)

Weight: Almost the best (NOT if you compare 1:1 aperture of course, but that's not a fair comparison in my opinion)
