Debian Stable and Ubuntu LTS would be a good enterprise distro as well, really stable repos, and easier to manage than RHEL, CentOS, or SLES and SLED, and Debian Stable has three years support while Ubuntu LTS has five, which, all in all, wouldn't be too bad a deal IMO.
Meanwhile on the homefront, Fedora, Debian Testing or Sid, OpenSUSE, Ubuntu standard or Ubuntu +1, or Arch would be better as you're not really running any critical stuff that requires as little downtime as possible at home like you would be in a professional setting.
In conclusion, if you're looking for a distro to run in enterprise, you'd be better off looking at Debian Stable, Ubuntu LTS, CentOS, RHEL, or SLES and SLED because of support and stability, while in the home, you'd be fine with Debian Testing or Sid, Ubuntu Standard or +1, Fedora, OpenSUSE, or Arch as you're not really concerned about stability on your home computer like you would be in an enterprise setting.
Just my $0.02.
