Mugen diff are maybe stronger than RC8 diffs, check the type of diffs spur on RC8T, helicoidal or normal, helicoidal is stronger and has a better efficiency.

Mugen, no question. I just sold my RC8T for my MBX6T and I'm so happy I did. Durability, design, performance, and weight are much better on the Mugen from what I've seen so far. My Mugen is 1/2 pound lighter than my RC8T was too with the exact same electronics and batteries.

It's helical and yes, helical gears are stronger than straight cut under most conditions.
