Hard to say, we need to see more of Fury. He did outbox Wilder, but so did Shpilka and even Washington until they got caught and KOed. The only difference is that Fury recovered and continued. Old Wlad is a good win, but Wlad didn't have stamina and reflexes at this point. Both beat Chisora. In theory Fury should win.
My first inclination is Fury via comfortable UD. Then I ask myself - "Wilder had Fury on **** street, and Haye could also bang during his prime, but as Haye was a MUCH better technical boxer, and a clinical finisher, could he have seen out the job Wilder couldn't if he did manage to drop him"? Of course Wilder is much rangier than Haye, but then again Fury has been dropped by the likes of Cunningham - who's not a patch on Haye.
