I have a preference for guns as old as me
but maybe I'm just plain wrong about these new "classics." How do they rate - shooting, fit, and finish wise?

I like this analogy, because in spirit, I can respect it. But in fact, the ‘01 emissions restrictions would INHIBIT the natural performance of the ‘63 engine. There is no such performance loss in the new vs. old ‘classic’ revolver. You might not WANT the IL or the MIM etc, but the fact is, the package PERFORMS as good or better and I would argue with tighter tolerances in machining.They're pretty, but to my mind it's like buying a '63 Vette with '01 smog equipment.

I had a chance to shoot two .45 Colt M-25's side by side, my old one and a new classic model with all of the stuff purists hate. The new M-25 was better fitted, tighter, had a better trigger (amazing!), and generally shot better. All good. But the new M-25 had those Godawful laminated stocks, IL, and MIM parts. The performance of the new gun was surprising and pleasing, but I still prefer my old one.
I have bought model 22-4s and 21-4s and would rate them as excellent in finish and shooting. I wish I still had them but that old buy,sell, trade routine I used to have got the best of me.
