It does, but truthfully, http://tree.celinuxforum.org/CelfPubWiki/SquashFsComparisons helps even more.

To summarize:
CramFS, and more particularly, SquashFS, have lower overheads in terms of CPU usage, and are thus better for cases where performance is CPU bound. It is also the cleaner solution. cloop is better at random access, and is therefor better where CPU performance is not the bottleneck, or when the access metric is highly random in nature.

Another interesting difference is that there is no mode for running cloop as a non-module. I'm sure one can be added, but it requires the file name to bind to at load time, so I'm not sure that's really feasible in cases, such as a live CD, where you don't have the file at boot time. In the embedded field, where there is not much use for a modular kernel, that is a great minus.
