Recommend an OSR

[aramis erak]

I'm kind of getting an itch to play an OSR game. I've looked at them periodically over the last couple of years but haven't yet recruited some friends to try it. The other day I bought Five Torches Deep, and just now I was looking at the free starter PDF for Dungeon Crawl Classics. There are bits of each I especially like and dislike. And I probably have others lost in the depths of my various hard drives.

Any recommendations for a particular system? Why?

In order of distance from actual OS rules
(Moldvay/Cook) or Cyclopedia. Zero distance. Available in PDF on Drive Thru RPG.

Mazes and Minotaurs. Very similar to D&D OE, just different enough to be fresh.

Neoclassical Greek Revival is an "OSR in all but mechanics" worth a look. Tempting me to run it, but the system also is just complex enough my players might balk.

While not properly OSR, and not my speed, Barbarians of Lemuria is a firm embrace of the principles with complete rejection of the (not really all that good) Old School D&D mechanics.
