I love Barry and can’t abide Wally but, since I doubt he’ll get much love, Jay Garrick.
Jay is just a heroic “soul”. Something has got to be done, so he steps up to do it. (And yeah, Joan’s not happy he’s out risking his life…AGAIN. But, even she knows he’s doing it because it needs to be done.
What truly sets Jay apart from every other Flash is that he is a natural born leader. He can lead the JSA, something Barry, Wally, or Bart are incapable of, none of them could ever lead the JL.
Barry & Wally might be better at “speed force shenanigans” but when the chips are down and a big threat looms, Jay is a leader that other hero’s will follow.
