For anyone that might be interested heres a set of rules that blends 5th edition and AD&D 1st edition very elegantly.

Yea, they are a pretty good mix and worth a look. I used to think it was actually the other Chris Perkins who wrote it. heh
For just browsing and reading like a book for fun, 1e set hands down.
As a player with Covid-restricted online play, have to admit that currently playing in a 5e game with the automated D&D Beyond sheet and dice has been really handy and makes the game flow well. Takes away a lot of the ambiguity for players as we can access the reference for every little thing on our sheet to clarify with the DM.
I have OSE and love the B/X but it's more as a keepsake so my kids can see what it was like. Also like to refer to it for the little things missing in 5e for dungeon crawling, etc.
For running a game, current feel is D&D 5e SRD, coupled with the Cubicle 7 Adventures in Middle Earth third-party stuff is a nice blend: it sets a particular setting, limits the races and it all makes sense. With all the extra WOTC crud kept in check and a few house rule limits on resting, it works quite well. If you run the game, you call the shots and can avoid all the 5e bloat, making it work pretty well.
