If you need to pick glass vs optical quality, I'd go optical quality all the way.

Actually those two scopes are in my list, more is that Askar FRA400, and i am almost confirmed or decided to get it finally, but i still have time before i order if anything will happen to change my mind, but from some results i saw out of this scope i feel good and accepting what i see, and it will match one camera i already have, so it will be done.
Now i am searching for third same focal length or FOV of FRA400, for my other cameras, i have three and i might add one more, so having 4 cameras is so much flexible, and for that i prefer to use two or three scopes, one is ordered which is a triplet new model FPL-55, second could be strongly this FRA400 [it matches QHY294M which i have nicely], then i am left with QHY163M and ASI1600MM, both have 3.8um pixel size, and i don't want to go longer focal length only to match pixel size for sampling as many told me, but who knows.
