The huge difference is in the tube mechanical stability, I focus the RCOS every 2 weeks or so and the secondary focuser/thermal management (fan/heater control) is insanely accurate and reliable. I havent colomated the RCOS in years.
If your willing to put the effort (im not) into countering these mechanical deficiencies, then you can save a lot of money for the same result. The old rule applies, less money, more effort for the same result, its doable.

Do you have some results that you could post please?
That would be only stretched examples - no other processing & at full scale.
