Joshua KO most likely. Close decision next most likely (probably given to Joshua regardless of how we all score it). Usyk more likely to win on points via dominant outboxing than to KO Joshua. IMHO. Chisora may have been stylistically more difficult for Usyk than Joshua would've been, but: 1) Chisora is sloow. 2) Chisora really lacks reach at HW. 3) Usyk wasn't really threatening to knock out Delboy. Now the relevance of this (IMHO) point by point: 1) AJ isn't exactly skipping around the ring like Fury, and yes he's been known to gas BUT he's not nearly as plodding as Chisora... Also bearing in mind if Usyk comes into this one significantly heavier than the Chisora fight then he'll lose speed from that and from being older. 2) There's a big difference in what you can do without getting tagged between having a 4" advantage in reach and a 4" deficit in reach - if you're trying to avoid bombs and combos this matters... If Chisora can land plenty with a disadvantage, AJ definitely lands something with an advantage. 3) Delboy has a decent enough chin but he's an easy target and been knocked out flush before - AJ is harder to hit without trading (especially if there's less speed advantage and a reversal of the reach advantage) and his only loss he was badly buzzed and quit, but it was a slightly bizarre one and there's hardly a pattern of AJ being easy to beat up and knock out as some posters seem to think. Put it all together... And I just can't see Usyk being able to do more damage to AJ without getting tagged than he did to Chisora - so IMHO that's KO probably off the table. With judges being likely to favour Joshua (even if they don't, the perception that they will be does the same job) and I'm not sure Usyk will believe he can get awarded the win on the cards without a completely dominant display or a KO... I think he'll almost have to try too hard, get knocked down somewhere in the mid rounds and get knocked out whilst chasing either his own KD or an unlikely KO in order to save any chances of winning. I could be wrong, there's an awful lot of unanswered questions around Usyk going in to this and AJ, for all his faults, is likely to have too much for this aging and slowing version of Usyk.
