I can't say too much about Lemmings Reunion at this point - it definitely shows a LOT of promise, but the current version of it is on Lemmini which I'm personally not a huge fan of. I'm very much looking forward to playing it once the NeoLemmix version is out!
Aside from my own packs (the Lemmings Plus series, and Doomsday Lemmings), I'd also highly recommend GeoffLems, GigaLems, and the cLemmings series (especially "Oh No! More cLemmings!" and "cLemmings Ultimate Edition").
It should be noted that those recommendations (except for GigaLems) are based on traditional Lemmix, not NeoLemmix, so the game mechanics will differ slightly from NeoLemmix (but on the other hand, they're practically identical to DOS Lemmings).
One final recommendation, if you haven't already played it (or rather, the levels in it), would be the "Extra Levels" Lemmix player. This contains all known official levels that come from alternate versions of the games that replicate the style of Original Lemmings, but weren't released in a DOS format. The majority of these come from the Genesis version of Original Lemmings, but there's a few from other places as well, such as special Amiga editions, a few levels found in demos that didn't make it into the full games, etc. There's also some remade versions of levels from platforms that don't so closely mimic DOS - in particular, PSP and Sega Master System. You can get the Extra Levels player here:
