I've had both;The Jewell feels like it has creep to me when adjusted over a pound. The TriggerTechs are very crisp. I also have always been concerned with popping a primer with the Jewell as they are fragile triggers. The TriggerTechs are priced right and are frictionless. The CLKR feature in adjusting pull weight makes it pretty fool proof. Each click of the pull weight adjustment screw is about ~1 oz. on the Primary.
