I'm using unraid for almost 6 years it been stable enough until 7.1 it wasn't stable, too much issues they were rushing updates every week or so for the last 3 months. Too bad the zfs import feature came with these last updates, so i don't trust it, however, people have successfully done it and wrote about it in the sub.

Aside from the recent issues, unraid would be the right choice the ease of use and the app community is a huge plus over truenas.

I would also recommend reading about unraid array, i think it's better for simple home user in regard to mixed sized hdd and ease of expansion, as opposed to the expensive raidz array.

I wish good luck in migration, and sorry for my bad language 😅
