Meh.. it's still only a 10". Quite a few newtonians would slay that, starting with the 16" at Mt Bowen.

And I know of an 11" with Intes optics at strehl 0.985 that would eat its lunch on double stars, lunar & planetary, at 1/3 the cost.

if you want sheer image quality:

Under 130mm, refractors rule.
130-275mm - Maksutov Cassegrains rule - primarily those with Intes optics, and the Skywatcher ones are OK.
Above 250mm big newtonians are the only practical option for most.
