I have 3 90mm Maks, a 1965 Questar Quartz Standard, a Meade ETX-90EC, and a vintage orange C90 Astro. I love them all for different reasons, but for all their plusses and minuses they can all deliver outstanding views and results
I like the Q for its versatility, especially when it comes to ease of setup, especially for imaging. It's optics are the best of the bunch.
I like the ETX-90 for its ease for travel and minimal accessory requirements; I can set it up on a picnic table and start observing or imaging after a 2-minute alignment procedure. And its optics, while not quite as bright and contrasty as the Q's, are most excellent.
Last but not least is the no-frills vintage C-90, also a quick scope to set up. It's so light and yet it's practically bulletproof. And its optics can hold their own as well.
The winner? It all depends on my goals on any given day, which is why I still have and will keep all three.
