Right now's a good time. The packages are about as fresh as they'll ever be, and is fairly easy if you've installed a Linux before.
You can always give it a try in a VM
Thanks. I've been loving Kubuntu for the past couple of years, but it does have kind of a 'corporate' feeling to it.
It's like "Hey, try our Snap packages! We've already set them as the default, because that's what our market research shows users want." "Wait, what!?"
Kubuntu is a good one, especially with the newer desktop PPA, and a lot of the user friendliness built in. Debian, on the other hand, would need a lot of that set manually, but it's likely worth it if you want a more self-owned system.
It's worth a try. Gotta try something to know if you actually like it.
