I watched whole Haas match and in my opinion It was far from best. Too much depended from errors, also a ton of serve points. Not so much great rallies though.
My vote goes for Navarro-Gonzalez. That was awesome latinos encounter with full entertaining package - aggressive tennis, many great points, celebration scream battle, a lot emotions during match including Gonzo hardtalk with umpire and some artistic shows where ball is in or out + hot chilian crowd. truly reminds me some of DC matches
