I use the VicMarc 3.5" when I had a Delta Midi, when I upsized my lathe I simply changed the insert size for the new thread size. I like the way it tightens and the quality is wonderful. I also bought one of the clones from Grizzly, but it is not much of a clone. For the difference in price I wish I had bought another VicMark, I'll do that soon and then donate the Grizzly to my AAW club for the monthly auction. The difference in qualit is well worth the price in my opinion.
Not sure why I bought the Vic to begin with, I think it was just a choice that I picked when I bought it. However, it has been much better than others I have messed with at AAW meetings. I might consider the Nova but only if it was considerably cheaper. I would guess at least 90% of my turning uses the Vic chuck at some point, well worth the investment. [
