Perhaps it should be by aperture. 4, 5,6,8, 10, 12, 14, 16, 17, 20 inch aperture of any type.

Greg.
You need to specify fixed (observatory) or portable.
And is cost an issue?
And a preference for type?
Photographic use or visual?
At each size, you could pick a "best of breed" for each type, though finding commercial refractors over 10" might be tough.
Some of the scopes will exceed a quarter million dollars.
