"Better" I believe but the better than another person has many variables including driving styles, loads, gearing, terrain, etc. In my thinking that's not definitive but as I say, better is believable as we all know the EPA equipment comes at a MPG cost.
I question when claims are made that someone is reporting a 100% increase in fuel mileage over what the vast community reports of 9 - 13 mpg towing heavy fivers. If those claims are true, then I want to know how that was accomplished. If an engine has the H.P. and torque numbers doubled, AND the fuel usage halved, AND there wasn't a serious issue with the engine before the mods, then I want to know how that was accomplished.
