First I thought 'Fedora?!? seriously???'. Last time I used Fedora (several years ago) I was pissed off when I had to learn that they didn't support system upgrades. So with every major release you had to reinstall the whole system, which is not that much fun.
But it seems they support system upgrades since a few releases now [1]. So maybe I should try it one day again, but as I fell in love with (stable) rolling releases, that might still be an issue :-/
