The retail version of Avid MC comes with Avid FX (and Sorensen, and BCC, and some more), which is basically BorisFX, which may be a little like Motion.
The educational version does not come with Avid FX (and the rest of the 3rd party package), but you can purchase it seperately.
The best thing about the Academic version of MC is that it comes with 4 years of free upgrades (as long as you qualify for the Academic license, that is).
Also, MC has a 30-day free trial version. You can check it out for a full month, then decide if you’d like to own it for that very low student price.
If I were a student, I would not hesitate for one second.
