Shooting benefits of metal vs polymer grip on 2011

Considering upgrading my prodigy polymer grip to the new atlas prodigy grip or the tti metal grip. Curious if those who have gone poly to metal can share their experiences. Besides feel of the grip im curious to know how recoil, handling, performance were affected by the switch. Ive heard monsoon tactical talk about how poly grips absorb recoil better but curious to get opinions. Thank you
