One other factor: On 18.04, I have found it nearly impossible to use the NVidia driver. After installing, whatever I do, nouveau takes over. This was not the case on previous Ubuntu versions. Even putting nouveau on the blacklist does not solve the problem -- somehow even if I put it on modprobe's blacklist, also in the kernel arguments, it somehow manages to start up. No idea how or why. I solved it before, eventually, I can't quite remember, but since re-installing my operating system I haven't figured it out again. I think I eventually had to actually move/delete the nouveau ko files, which is a very destructive way to deal with a problem and interferes with apt, and even then they got re-built and re-installed by dkms and took over the display again! I did find a permanent solution which escapes me at the moment. Anyways, it would be good if NVidia and Ubuntu got together and at least made it easier to make use of the official driver.
