I can kinda see why you wouldn't like the champions aesthetics, I personally am a fan of them and thing the model outclasses WW's in pretty much every way. He looks alot more primal and vicious.
As for the mechanics trying out fury combos is so much fun, if you get a fully stacked tooth necklace you can q like 3-4 times in a row just with resets. In team fights the ferocity roar is really good, 15 percent of total hp really helps, I feel like he scales a little better than other bruisers because he seems to fit into more useful late game roles and you get alot more value from his abilities because of how spamable they are. I love him.
