They should just call it the Ten Best WotC Third Edition Adventures.
I don't think I'd even call it that - more like "This is the only 10 official adventures we have out at the time of printing"
1E has a lot of classic adventures, not necessarily because they were good, so much as they were the only ones available and there was a lot of shared experiences (Some were quite good however). If you started talking about, say, Tomb of Horrors, you'd get a lot of nods because other folks had played it as well.
For the most part, I mostly remember 2E for the settings, not adventures. The only ones I can think of that really stand out are:
- Labyrinth of Madness
- Return to the Tomb of Horrors
- The Mud Sorcerer's Tomb (from Dungeon Mag - apparently fairly popular, as it was reprinted twice)
By 3E, there were tons of adventures available - and most of them weren't coming from D&D's publisher. The ones that stand out to me:
- Sunless Citadel
- Forge of Fury
- Shackled City
- Of Sound Mind
- Red Hand of Doom
- Return to the Temple of Elemental Evil
Sadly, for 4E, I am not really familiar with the adventures. The only ones I have heard much about (or played) are:
- Keep on the Shadowfell (if only because it was the first adventure release)
- The Slaying Stone
- Thunderspire Labyrinth(?)
I think, overall, the gaming base has gotten too fractured for there to be many more "classic" adventures down the road. With the general disdain leveled towards WotCs adventures and the fact most adventures now appear through Dungeon or part of other sets instead of stand-alone adventures we'll see fewer and fewer in the future. If 5E opens up to 3rd party publishers I'm guessing we'll see
even fewer as the "everyone's familiar with this one" aspect of the classic adventures will be spread across the large volume of adventures available.
