I know I'm probably in the minority, but I despised running 1e AD&D. I stuck with B/X D&D for a long time. You're right that we rarely went beyond the Basic/Expert sets with our games, but that's because the Expert set was the "sweet spot" - once you got up to Companion level characters you were fiddling with building strongholds, running domains and conquering your neighbors. That was fun once, and taking those characters into Master levels was also fun, but really, the "best" games of my youth were the ones hitting 3rd-10th levels.
See, that's interesting. Perhaps my favorite thing about BECMI, as opposed to AD&D, was that the sweet spot (IME, of course) went all the way up the chart. BECMI's "adventure path" (the B series, the X series, the Karameikos civil war, then CM1
Test of the Warlords up through the M series) worked all the way for me. Certainly, the reduced array of options and the continual scaling of monsters to match PC power levels (Large and Huge dragons, Gargantuan creatures) were turn-offs, but minor ones, in the scheme of things.
IMHO, BECMI had a lot of things that 3e should have picked up. Reached 15th level? More powerful than pretty much everyone else in the implied setting? Fine. There's a wild continent for the taking. You've reached the pinnacle of your success as an adventurer, so now go and found a kingdom in the unknown lands. Oh, and with the unknown lands come new and terrible threats, only now you have to defend thousands of subjects, lead armies, and negotiate the fate of nations.
Reached 25th level by governing your kingdom, winning wars, exploring entire mountain ranges crawling with dragons, and forging out into the unknown North? Guess what? You're now powerful enough to attract the attention of the Immortals, beings to whom an entire world is barely a speck of dust, and who represent the cornerstones of the multiverse. Become involved in their infinite metaphysical struggles if you wish... and perhaps, one day, you can ascend to their ranks!
I for one think that it would help a lot of DMs to have a firmly implied philosophical divide between low-, mid-, and high-level games laid out directly in the rulebooks, including rules to support these different levels (dominion, warfare, and plane-traveling rules for higher-level PCs, etc.) To a certain extent, these things exist in 3e as it stands, but they're sort of haphazard, and in any case certain powers (plane travel, etc.) are available in the game IMHO far too early.
It is quite possible that 4e's three-tier divide is an attempt to replicate the BECMI divide, in philosophy at least. I certainly hope so; perhaps I'll even convert those old modules!
