I like them, they are just pleasant to look at. Yes, they're spammed as fuck, but as long as all the details don't bother too much when you're actually playing? Detailed maps are cool. And who said you can't have some places that are detailed more, and some that are more basic? Having this kind of contrast is a good thing imo. Just like having places that look like actual places and not some abstracted shit.
I mean I agree, some maps here are just too much, and some just not that good, but some are just perfect and look pretty legit. More believable than this "symbolic" kind of mapping you often see. I'd play that.
