For me, it was perhaps simple-scan, a very simple and efficient GUI to scan documents. I used it with my Brother printer / scanner and it works like a charm. Especially since I do not scan stuff often, so a program with more complex UI would have the effect that I forget how to use it until the next time.
Wasn’t too difficult as they already offered Linux as a supported option. But I had to justify it. I was already using a linux VM for all my actual work. So I complained about all the buggy behavior I had experienced. Didn’t have to exagerate too much. I was properly modivated after IT sent out an email announcing the forced migration to Win11.
