Just curious.. what do people consider to be the most popular and/or influential edition of D&D (besides 0e of course)?

5e has been hugely popular and has brought a lot of especially new people into the game. But 3e took a dying (dead?) game, made it wildly popular as well, and turned it into the basis for a Lot of other games from other genres (the D20 system).

As much as I appreciate the streamlining that happened with 5e, my money is on 3x. Any thoughts?
