I do agree about the Ubuntu part. For the updates, if the intent is just to test KDE in a live environment, this part should be up to date and frequent updates should not be an issue. I would recommend against using KDE Neon daily though. Or Ubuntu by the way. It used to be a really good distro, but it's not so much today I think.
