As well as the already mentioned GPL versus GMGPL issue, you need to
consider if you are intending to perform any embedded or cross compiler
work with Ada.

For example, RTEMS and AVR-Ada both use the FSF version as their base
while MaRTE appears to need the AdaCore version.

My personal preference is for the FSF version (because of it's GMGPL
license) even when I am not using RTEMS or targeting a AVR processor.

Simon.
