Still not seeing any massive differentials. New 52 Superman perceived Barry in the span of a nanosecond hence why he was able to flick him with his finger. He also ripped Doomsday in half. That's pretty damn forceful. He wasn't faltering in any department in any noticeable way. And I don't remember it ever being stated that New 52 Barry was any slower than pre-FP Barry, so that the universe world around him was less powerful in compassion doesn't wash either. Judging just by the present materials, difference in terms of tangible feats were quite negligible.
