Rolling Bender Pro: Light, easy to install. Can be installed on most Strat and Tele style bridge. They offer individual saddles and traditional Tele saddles. Con: Picking hand needs to move to use it and it's a little harder to do gradual bends. The latter might improve with technique over time. I wish they offered angled levers or something that would allow 2 Rolling Benders independently. Hipshot B Bender Pro: Just tug on the strap and no need to move either hand. Very good for gradual bends. Con: Requires extensive surgery. F#$%^% heavy. Limited to the Tele shape.
