So, it's been a few days, the poll's kinda been forgotten, and the results?
Wally by a pretty hefty margin. Not a single vote for Barry, which I find surprising. He's always been THE Flash, even for as long as Wally was doing the job. I agree that Wally's faster, but surprised that Barry got zero votes.
Granted, my sample size isn't exactly representative of anyone or anything. ;)
Out of curiosity, I did a Google search to see what the internets said, and there was one quote I thought was perfect. Paraphrasing, "The fastest Flash is whoever is headlining the current Flash title. Because who wants to read about the second fastest man alive?"
