The Framework is a beta product, at best. If you know that and are up for the challenge, go for it, but if you want something you're not going to have to fiddle with every time you want to do anything on it, pick something else.
Ubuntu is a bad choice for newer and esoteric hardware, a rolling release distro will have up-to-date kernels and userlands in comparison.
