I'm sure some more knowledgeable folk will chime in, but my take is the ZAOII are 1.25", and the latest reincarnations from Baader Planetarium. They were a re-run if you like of the original Zeiss Abbe Orthos, which were amazingly popular, and crazily expensive.
I have had a few through my hands, but never really stuck with them, too costly for my frugal tastes. I do have a full set of "original" CZJ orthos, the .96 versions. They are lovely, and I use them often.
At the end of the day, they (like anything) are worth what someone will pay for them.
