As mentioned, colo is pretty much regional. The "best" DCs will probably be pretty much limited to your closest large metro areas.
That said, there are major national and global players in the market like Equinix, Switch & Data, Verio, Digital Realty Trust that may have more of a national reputation for service quality. A lot of people consider Equinix a very good premium colo provider for example - with pricing to reflect that.
Still even the largest metro markets - SF Bay, Los Angeles, NYC, Dallas, Chicago - are probably dominated by local/regional players vs. just national players in the colo market. SF Bay has Hurricane Electric and 365 Main, for example, as pretty major local colo providers, though 365 Main is growing its presence nationally.
