I have seen great results from the Esprit triplet APOs. Not to say the WO scopes aren't great too. I would steer away from doublets as claims they are APO are usually marketing BS. Agema Telescopes excepted.
The bigger the better, If you have the budget the standout there to me is the Esprit 120.
I would consider:
Triplet and has an FPL53 element.
A decent focuser.
Plenty of examples of user images using these scopes. Astrobin is the best resource for that.
WO are great at machining. Their machined parts are works of art. I am not so sure about their scopes. Perhaps they are. But they also BS about APO and call FPL 53 triplets fluorite sometimes. Fluorite is a crystal and a high end lens element like Takahashi and TEC use. It is superior to FPL53 which is why they call it that. FPL53 has a lot of fluorite in it but its not fluorite.
You don't need a 3 inch focuser for an APSc camera like Fuji XT2. 2.5 inch would work.But if you plan to go full frame one day 3 inch is safer.
