I use hitecs in my large 3d planes, Jr in my helis jut with jets I'm going back to futaba. The new HV sbus servos are great, all the servo program options. The seem to develop less slop thany jrs. I think all have pros and cons savox are good as well the heli guys who can put servos through some abuse really like them. Go with what fits you budget, even the top end servos go bad without warning.
