I do pretty much the same thing with monit, except I don't use mongrel_cluster. Because monit needs to handle each instance of mongrel separately, I didn't see the point in using a clustering tool to handle single instances. It's a minor difference, really - specifying the mongrel_rails options in the monitrc file vs. the config/mongrel_cluster.yml file. Either way, I use monit to restart a mongrel cluster (or "group" as monit calls it).
I'd say monit offers _more_ than mongrel_cluster, but I'm no expert.
