I'm not so sure. There is a pretty decent sized price margin between the two (which is why I ended up with the cheaper ones).
Here is a quote from a listing:
2 New TRAXXAS BRUSHLESS E-MAXX DIFFERENTIALS for Front or Rear. These were removed from a new 3908 Brushless E-Maxx. The 3903/3905/3908 E-maxx truck use this same diff.
This is Traxxas's strongest diff for the E & T-Maxx trucks. UPGRADE YOUR 3.3 T-MAXX DIFF TO THESE FOR BETTER DURABILITY!
The E-Maxx differential is different internally from the T-Maxx differential in that the internal cup has bracing and steel pin guides. This makes it stronger and more durable.
And then the two different diagrams show some differences:

4907 diff view
I just want to know if people had any experience with both diffs, and had any insight as to how long each would last in a moderate brushless setup.
