It's not just that fragmentation results in lack of polish. Having many distros means that when I want to figure out how to do something obscure, or encounter an issue, there's less likely to be someone on my distro with the same problem. But more importantly, I often don't get any good results searching "*issue* *distro*", because the issue is at a different layer in the stack. I have to know whether it is a distro issue, desktop environment issue, kernel issue, systemd issue, X11 issue, etc, which is difficult for new users. Compared to Windows and Mac which aren't modular in this way and therefore don't have this problem.
