Get the Prothane one... The ES Mount is around 1/2" taller than the stock LS1 mount. That extra 1/2" of the ES mount changes the pinion angle because the torque arm is attached to the trans. It helps to not use the torque plate and grind down the nubs on the mount but then the ES mount fails after a thousand miles of street driving. so I vote to get the prothane mount and just install it and go.
All poly trans mounts will cause a lot of vibration but it calms down after a couple thousand miles of driving.
