Mocha has our vote as well. It's saved our skins and rescued some almost impossible shots. Like Robert mentioned, the tracking info export to AE for complex stuff has allowed us to do some nice stuff.

It's certainly worth a very serious look. Like all pro level tools, it's curve is a little higher, but then again...so are the results!

Any of the motion stabilization processes will soften the image, but Mocha, with its high end tracking, creates less softening than Mercalli, or the AE tracker.
As I mentioned, once the stabilized clip is on the timeline, you can apply the unsharp mask filter in PPro and the image sharpens up to very, very near the original detail.
The 10 bit CFHD.avi provides the data headroom to get away with this magic.

The only problem that I've run into with Mocha and blur is when the blur is not consistent from frame to frame. This seems to happen on particularly "unruly" shots. Sometimes fiddling with the settings in Mocha or using an alternate planar surface fixes this problem. But for most stabilizing jobs, the combination of Mocha and Cineform is truly magical.

The 64 bit version of Mocha will be released at about the same time as Adobe CS5. With more physical RAM available, this should help with tracking and stabilizing full HD and higher clips.

Ok thanks everyone!! Most of the shake I am talking about is just from holding the camera. Sometime a little movement or a short walk cause more shak then i would like.
