They concluded that Orion had the best. I got an 8 inch Orion three months ago and then and Orion 10 inch dob a month ago, because I wanted to do more deep sky stuff.
Larger ones are better for galaxies and nebulae and clusters.
I am very happy with both telescopes. Be aware that the bigger dobs can be quite bulky to transport and carry. My 10 inch tube weighs around 35 pounds and is quite unwieldy to carry. And hard to transport in a car, but doable. Hope this is helpful.
