The real test of any mount is can you get round stars at 10minute exposures at a decent focal length. If you can its a winner.

Other things help but are not essential. That's the guts of it.

Also with a good mount round stars are not guaranteed. A good PEC and accurate polar alignment are pretty important. I use Sky X Tpoint for getting perfect polar alignment. Its an amazing tool and you see the results immediately in the very low autoguiding errors.
