After initial satisfaction, I stuck with Nova partly because all the jaws are all interchangeable, except for the 12 screw jaws on the big Nova Titan chuck.

I haven't bought any new in the last three years so if the quality has gone down I don't know about it.

While I don't know (or want to know ) why you have twenty, IMO VicMarc machining and tolerances are better, the backplate and insert are much more refined as well.
i like my Novas, they get the job done and the price is always good. The slop in the jaw slides is more than it should be and the inserts are a joke.
It's always a balancing act. there is no single brand that can tick all the boxes.
