Here's the 28-70 wide open tracking a running dog. Yes, it's not as fast as the RF 70-200, but it's still pretty darn quick. 
If it matters: I sold my RF 24-70 for the 28-70, and also own the 70-200 2.8 and 100-500.

There is an astonishing amount of conjecture and uniformed opinion in this thread.
