I have used several JPs and several Electron and now always buy Electron with a GS-200 controller moving forward. The Electron gear, in my opinion, are the best available. They are incredibly strong and well built. Maybe slightly heavier than JP but not by much. The only thing that is annoying with them is that they need loctite and some flat spots on the internal pins. Unfortunate that the factory doesn't do this for us. JP gears are OK too but I had my share of burned actuator and the gear controller (orange box) is a total piece of garbage. They will burn eventually and need to be replaced with a Xicoy gear controller.
