I looked at CoRD briefly once, back around the time I first took a look at TSClientX. It seemed too new and immature at the time, but I’ll have to continue to monitor the project.

One other thing I’ve noted about TSClientX that I didn’t mention above: it automatically maps the Command key to the Windows key, so you can use Windows key shortcuts inside the Remote Desktop session with the Command key on your Mac keyboard. Very handy for someone like myself, who uses the “Run…” dialog box a lot.

I’m sticking with Microsoft’s RDC implementation for the moment, but I have high hopes for this app.
