It's complicated.
I started with OD&D in 1977, though Moldvay/Cook/Marsh was immediately adopted at the time it was released.
OSR-wise- I'm definitely more into the OD&D aspect, and I was all gung-ho from C&C original publication, through OSRIC & S&W (core) up until a year or so ago.
These days I have little use for the gazillions of clones/retro styles, except White Box, nor much use for what I'm seeing for "adventure material". Like the D20 era, for every great product, you have to sift through mounds of mediocre crap to find something worthwhile. To catch my interest, you really need to knock it out of the park with thematic/fictional elements and clever use of mechanics- Games like Encounter Critical, Seven Voyages of Zylarthen, Astonishing Swordsmen & Sorcerers. Modern OSR seems to be all about two questions-
"How edgey/old school punk" can I be?"
or
"How can I make 5E more old school?"
I have zero interest in either. Instead, I've gone back to/rediscovered my original and early 3PP materials for inspiration.
