Panos - I'm certainly very happy with the Spektrum ones. Being HV, I'm just running them direct off a 2S 1500mah LIPO through the VX1n rather than using a BEC or the like. I'm no pro-pilot, but them seem very good quality in themselves. They feel very solid and seem super-smooth on the heli.
Difficult to know how to objectively compare servos, other than published specs ... Otherwise, both are HV, both are metal gears .. I can't comment on the JR ones, but the plug-in cables for the Spektrums are really nice. Mine came pre-shielded too which was nice!
Looking at the pictures of the JR locking mechanism, I would say the Spektrum connector looks like it may be a bit more solid too ??
Spektrums seem to be faster and have more torque?
