There’s two models - the Duet 3 which comes with a Snapdragon 7c Gen 2 @ 2.55 GHz CPU, and the 3i which comes with a Intel Celeron N4020. I would rather use the Duet 3, due to the cover, and since I am already familiar with the feel of the device due to having owned a Surface Pro 4, but I’d like to choose whichever works best for running Linux.
Edit: Just for additional information I’ll be using it as a note-taking tablet with xournal++, not for any heavy tasks
This is not true at all. There are tons of Linux Distros running natively on ARM.
Debian, Ubuntu, Fedora, etc.
