The electronics and gear train is different to give a better torque and improved speed.Also the dead band is better. The servo dead band is measured in microseconds, and is an indicator of the "electrical slop" of the servo's electronics. To simplify, it measures the resolution of the servo.

What I also like in the DS95, so the new DS6125-E servos is their dimensions. F3X sailplane fuselage are usually very thin, making the radio installation sometimes tricky. Using these servos made me to save place on the servo tray and have more space for the receiver and the batterie. I appreciated it on the Vampire for example.
Below is the comparison table between the DS95 and the DS6125-E
