IMO the KTF tour was the best the band ever did. Jon's voice was at its peak, they still had Alec's backing vocals, and the live sound benefited from the slightly stripped down arrangements of keyboard parts (less washed out). Plus the setlists of course contained the KTF tracks.

By the TD era, Jon's voice was slightly declining and Alec was gone. Still some awesome stuff (I'd Die For You! These Days!), but not QUITE as good. Same for the NJ tour.
