Actually, a "live upgrade" is the preferred method for Ubuntu upgrades - and it's perfectly safe to do either over the net or from a cd.
Another benefit to Ubuntu is that they have an LTS version - which is absolutely necessary if you plan on setting up a production machine.
In the end however, if you're a decent admin, Linux is Linux and the distro you pick doesn't make that much difference (in general of course).
