I think 2E's big advantage is the quantity of TSR-created material. Today's OSR scene now produces more D&D-compatible material in a single year than TSR did during its entire lifespan, but it tends to have a different flavor -- more gonzo, often more gritty -- than the 2E stuff.
That said, I think the actual 2E rules were often rough around the edges, rarely balanced, and still had too many charts to look up things in the middle of the game (although obviously it was better than 1E was in that regard).
If I were inclined to play a 2E game again, I'd probably get a good retroclone or a non-retroclone 2E compatible OSR game that cleaned up the ruleset a little, reorganized things and maybe tweaked a few of the game's issues, and use that to run 2E settings and adventures with.
