FWIW I'm a (developer turned) manager who took over a team that was using tailwind and said "hey if you wanted you could do X or Y or Z as an alternative to tailwind..." and everyone metaphorically gasped in horror and said that tailwind was better than anything they had collectively done before.

I didn't get it at first either but I think perhaps a surprisingly big part of it is the fact that our UI is based on React and having everything contained within each component so you don't have to go hoping around between files is much nicer. And then it's just a thorough, tasteful and well thought out framework based on modern principles.
