navX-MXP has expansion IO and mounts directly into the RoboRIO MXP port; it has SPI, I2C, TTL UART and USB interfaces. Specifically designed for plug-n-play use in FRC. Great for use as a FRC Chassis Orientation sensor. $99.
navX-Micro is smaller (2x2" square), and only has I2C and USB interfaces. Great for FTC robots, and also placing on arms and cameras on FRC robots if you want to measure their orientation separately from the Robot Chassis. $79.
Other than those differences, the sensor and motion processing firmware is the same.
The RoboRIO libraries (C++, Java, LabVIEW, Python, C#) will work with either, no code change required except to specify which interface to connect to it with.
We are aware of teams who are using both simultaneously on a FRC robot, which is also supported.

Also, please note that there's currently an issue w/reconnecting to the RoboRIO if communicating over USB if the navX-device gets reset. Kauai Labs is currently working with National Instruments to resolve this issue, but until it is resolved, we are not actively encouraging using the USB interface in competition settings. We'll notify the FIRST community once this issue has been resolved.
