Best Linux Distro for ARM chromebooks? (in terms of packages)

I love arch linux on x86_64 because of it’s rolling release model and a ton of packages on AUR, and thanks to ChaoticAUR, possible to install without building it from source first.

But I’ve got ARM chromebook, and I wonder - which distro has more packages for this architecture? postmarketOS is looking great, but I don’t like Alpine. There is Arch Linux ARM, but AUR packages were made primarly for x86_64 architecture, so I don’t know how many of them will be compatible. Or some other distro that supports arm chromebooks?
Give your expierence on this platform.

Archlinux ARM just sucks in general. It isn’t a well maintained distro. Debian, Fedora, and Alpine are gonna be the best options.

Possibly Gentoo, but idk, I’d probably stick with what WeirdTreeThing recommended. I’m not too familiar with Arm or Aarch64, so take my recommendation with a grain of salt.
