From a bit of investigation I think TeamCity scores with the Build Grid concept whereas it seems CruiseControl runs on a dedicated machine.
As far as I know, CC is able to do distributed builds, although I don't know how well it is supported.
Another features that's missing in the feature matrix is that CC is open source - and the code is actually good enough that it isn't too hard to write your own extensions.
