Well the Euphoria engine has for a long time been excellent. If you are just looking at reaction to bullets, IV is probably still the best, though Fallout 3, The Force Unleashed games (not bullets....) and Stranglehold are the games I remember as also having great animation
As for all round animation, the king is obviously Uncharted 3 atm, but Max Payne 3 does look like it will be posing a very serious challenge to that throne
