"How do they fare?
OK, so here we see the runaway leaders is Ubuntu. We can see when
they’re six monthly cycles are released, with Fedora and
OpenSuse a distant 2nd and 3rd.
"Latest releases - the showdown
So here we see that in the final quater last year, all three big
players released their latest iteration. You can clearly see a
strong correlation between news articles and the release of each
distro (obviously!). Ubuntu outstretches the other two, but Fedora
is a clear 2nd, with OpenSuse, taking third prize."
