The Mobileease is just a motorola 8880 or some model like that. I haven't tried the Parrots, but based on Parrot having a display etc I may be more inclined to move to them next time I get something installed.

The bigger problem is finding a good spot to put the phone with a holder. A lot of interference when you're on a call at least with GSM phones near the center of the front seat area.
