I feel that Fedora is the closest of a rolling release without the hurdles involved into running a rolling release.

I've been using as my main OS for some time now, and with the exception of rpmfusion breakage, Fedora been quite stable.

So, I'd say it's close do OpenSUSE Tumbleweed, with some release cadence and support.

I don't find Arch to have many hurdles (Until there is something broken and placed on the webpage). They should have some tie in with Pacman to say read the front page before updating or front page was updated on date so and so ... Would fix the last hurdle that Arch has over other ditros.
