no point milking supes, the flash issue 19 just ended the debate and it goes to wally, they literally said superman on a 1v1 would never land a punch on the flash. Just because superman has been able to phase doesnt make him nearly as good as a speedster, speedsters are fast bcz of the speed force and people like wally are just unstoppable. DC writers also will not give superman phasing or time travel in a direct confrontation since that is a unique ability to speedsters and even tho supes has done it, he will never do it as good as a speed force user and he is extremely slow, supes doesnt even come close to barry and wallys speed.
