Jeez, this is fast and loose, but...
The JSA (Robinson/Johns)
The New Teen Titans (Wolfman Perez)
JLI/E (Giffen/DeMatteis)
Doom Patrol (Morrison)
World's Finest
Honorable mentions to Hal 'n' Ollie, the Birds of Prey and a few incarnation of the JLA/JSA. I want to put Batman and Robin on here, but frankly Damien's kind of ruined the dynamic duo for a while.
