Re: Rumor: Joseph Gordon Levitt will be Batman in Justice League film
9 out of 10 times Flash will beat Supes if they are being serious. Barry Allen, specifically, is so overpowered its ridiculous. Like MrMister said, he LITERALLY is Speed.
Wally is fucking better than Barry tho. If they did JL, they presumably would stick closer to the JLU roster except for maybe Green Lantern. But who knows, apparently the script for GL2 is really good (spoilers: Sinestro Corps War adaptation) and John will get introduced so he can be in the JL movie.
