User blog comment:Awesome!/Luffy stronger than ace?/@comment-1055368-20110127214359

In terms of physical strength they were even in the Arabasta Arc although in terms of Devil Fruit power Ace's power was far greater. He managed to slightly damage Teach who is one of the strongest characters in the series. After Luffy's 2 year training he's likely a whole lot stronger than Ace ever was, at least in Gear 2nd or 3rd.
