Greatest home run in MLB history?

  Being a Tiger fan my whole life, I simply can't vote for Gibson wearing that Dodger uniform. I understand all that was connected to the moment...Gibson injured, barely able to walk, hitting it off of a wonderful pitcher, etc etc but because of my age and because of the historic account that everyone has seen many times..."The Giants win the pennant, the Giants win the pennant, the Giants win the pennant", I simply have to go with Bobby Thomson's walk-off homerun against the Brooklyn Dodgers in 1951 sending the Giants to the World Series. What a great moment in recorded broadcast history!

  My personal favorite was Lenny Dykstra's walk-off, 2-run HR in Game 3 of the 1986 NLCS to beat the Astros at Shea. The place just went bonkers, it was already all jacked up for the Mets' first postseason home game since '73, and that just elevated the insanity to a new level.
  
  I may be biased, but that '86 NLCS HAS to be considered one of the best of all-time. Dykstra's walk-off in Game 3, Mike Scott's dominance in Games 1 and 4, the classic Dwight Gooden vs. Nolan Ryan nailbiter in Game 5 (Mets won in extra innings), and the all-time legendary 16-inning Game 6 that sent the Mets to the World Series (Mets were down 3-0 in the ninth, and sent the game to extras) ...

  Also went with Gibson's. I remember watching that and seeing Eck saying "wow!!!"
