I admire both, but I lean towards Louis by KO. Fury has a lot of tools to give Louis an awful tough time of it, true, but I also think Louis is a tremendous puncher, with blazing speed in following up a well-landed, well-timed blow, he had a lot more skill and finesse than Deontay Wilder, and was a tremendous finisher who didn't just look for one big bomb. Louis set things up with crisp jabs, worked the body, and had pinpoint accuracy to the head. He knew how to slide into range, dip and roll away from blows and come right back with a two-fisted attack or counter attack. But, of course, Fury is huge, tall, very big, fast, has some pop too, and could hold, lean in, or roll and step away, and keeps a solid pace too. He also has a lot of heart and an underrated ability to recover from big blows. Not saying it would be easy, but I give Louis the edge, especially in a 15-round contest.
