I've been playing with the 2024 rules in Adventurer's League, which just started requiring rather than encouraging them a few days ago. So far there are more things I like than dislike, but some of the background rulings annoy me (more of an AL thing than a 2024 thing though, like feats from old backgrounds not being origin but being uncategorized instead). I would say my biggest complaint about the 2024 rules themselves is Ranger being so focused around Hunter's Mark that several subclasses no longer work smoothly (including Beast Master, which is actually in the 2024 Player's Handbook). I used to have a few rangers, but now I can't think of any that still work except maybe my Swarmkeeper (who doesn't use their bonus action as part of their subclass).
A bigger problem is lack of support on DNDBeyond, which is essential for me since I play exclusively online via the Beyond20 browser extension and (usually) Roll20. There are so many things broken with DNDBeyond's implementation of the 2024 rules that it's really annoying, and many of them can't be homebrewed around because of site limitations.
