Just from the point of a consumer trying to get work done on my machine and deliver things in a reasonable time frame.
I expect to be able to flash a USB, plug it into my computer and have things work. The default settings for installing Ubuntu do not let you use 4tb drives without custom partitions, not ideal.
And RPM Fusion straight up doesn't work with fedora, have to boot into a cli and spend a few days trying to get the closed source drivers to work with no success.
