If I found that as a treasure map then I would enjoy going in. Lots of twists and dead ends on that top one which would be hard to describe as a DM or map as a player, unless we were playing with done out terrains and minis.
I would say no. And thats despite (or maybe its because of) the fact that I know what those maps are and who drew them (and I won't spoil your fun either, Quasqueton). Its old school, absolutely, in the same sense that a random dungeon filled with random creatures, without rhyme, reason or theme, is "old school". I moved past that style of adventure-creation 25 years ago.

Loads of edition-independent Greyhawk goodness... maps (good ones!), magic, mechanics, mysteries, and more!
Hmmm. I fail to see how one can judge the quality of an adventure simply by the maps (and yes, I also recognize those, Q... ) What the GM chooses to do with those maps will have much more bearing on the fun factor than the actual layout of the place IMO.
It does not look like it would be an easy task to map the top page, but again, that may be intentional and it might be a lot of fun to find ones way out of that maze, or not depending on how the GM handles the situation; but the maze itself does not automatically equal unfun...
I put "maybe" because it's just a map. It's like handing someone a map of New York City and saying "Do you think you'd like to visit?" without telling them anything about the place.
They're pretty to look at, and it gives me a sense more of being a setting than a single adventure. But it's all about what you do while you're there.
It depends on what's in the dungeon. Were that set of maps DM'd by its original creator, I'd probably enjoy the adventure, since I know the adventure would be wild and wonderful ... but the average Dm might just make a hash of them.
Those are the original Greyhawk Castle maps, aren't they?
