I take issue with that statement "Harry didn't technically beat Voldy". While it's true that it was Tom Riddle's own backfiring spell that killed him eventually, I think that was the whole point of the very long story.

As Dumbledore told Harry, Riddle was unconcerned with Goblins and Elves, and didn't understand wand lore because he didn't consider any of that to be important to being a good wizard. Those things resulted in his downfall.

Harry proved himself a better wizard because he understood.
