Well both can easily be his best. I thought the "love story" in Heat was great and added to the character.
Collateral Damage? HELL no!
My avatar is Tom Cruise from Collateral which is a great near-masterwork of a Neo-Noir thriller. Only the ending that didn't keep up with the rest of the movie was the problem. The direction, acting, music, cinematography, etc. All great. Tom Cruise should've been nominated for Best Supp. actor. His best performance after Magnolia. It's my favorite movie.
