Listed are the ten oldest well known custom missions that I can think of. Which ones still hold up as a high quality set in your opinion?

I'd have liked to also have included Konflict at Karon and Obsidian (1999) & Project: Hydro and Lost Levels (2000) but poll option limit doesn't allow it unfortunately. But they can definitely be mentioned in comments still.

Definitely voted for the majority.

Haven't played these in ages. Would need to give them a playthrough first.
I would say Entropy 1 and 2 and obsidian would have to stand the test of time as that style of geometry is very much what Luke and Dan are building for Overload now.
