I used to distro-hop until 2017 when I started using Gentoo as my main distro. I did not have the same experiences as you with Arch but I tended to avoid the AUR. Ultimately Gentoo has kept my attention by being more flexible rather than having negative experiences with Arch.

I suppose I still distro-hop a little bit on an old laptop I’ve got but that one alternates between Debian and OpenBSD; also its primary use is a terminal for SSH’ing into my Gentoo desktop from the sofa.

Probably the only distro I’ve had a truly bad experience with is Manjaro. The additional repo that it comes bundled with creates more problems than it solves. Also - although this never affected me personally - the story about developers asking their users to reset their system clocks to accept an expired PGP key is an absolute scandal.
