Apart from Gentoo where you compile your own kernel, I don’t think you’ll find a better selection of kernels on any other distro, than on Arch.
You can install linux-lts
from the repos if you want the LTS kernel (currently 5.4). If you need an even older kernel, you can install it from the AUR.
For example, my laptop only runs smoothly on version 4 kernel. There is no problem running 4.19 on Arch, you can find it on aur.archlinux.org if you search for “linux 419” (make sure to install the headers, as well, of course). When you install it, it will just be another item on the GRUB menu.
Keep in mind, Manjaro is also based on Arch. If it is possible on Manjaro, it’s possible on vanilla Arch, too (as well as on EOS, of course). Manjaro just makes choosing a kernel a bit more streamlined, but they have not invented the wheel
