Yes it is true that glasses have gotten better and closed the gap to CaF2 but I think with workmanship you get what you pay for.
Seems everyone focuses on chromatic aberration as the big evil of optics and very little is mentioned of the actual work that the glasses undergo. I am sure the Chinese have opticians capable of outputting objectives that match the likes of Tak, TEC and AP but I think most of their product is built to a price and thus fall short of the premium brands.

Don't forget the perfect Tak FSQ-85ED/106ED/106EDX/106EDXIII/106EDX IV/130ED.... all incredible telescopes, highly coveted by top imagers globally (almost as much as the FSQ-106N Fluorite).
I joined the A-P side recently, and find them every bit as wonderful as the Taks.
