I know I'm late and this is not going to change the outcome as I actually have Deku winning after all
HOWEVER
saying observation Haki and Deku's danger sense + analiytical prediction are in the same tier is bordering on criminal
Kenbun allows the user to sense other's emotions, intent, read their thoughts, sense their strength/powerlevel and likely more that I'm currently forgetting. It allows a literal blind, old dude to be at the top of the main military power of the world
(Fujitora isn't that old I know, it's for dramatic effect)
We see kenbun users literally call out what non-kenbun users will do before they even start moving while knowing in detail what's going to happen.
(keep in mind this guy states that his "mantra" training isn't complete) There was supposed to be a link there, I have no idea why it's not here, it was the trial of balls where Satori predicts Luffy and Sanji b4 they even move, if anyone can get those pages here I'd be grateful
Don't get me wrong, Deku's predictions are impressive as well...they just...don't really compare.
Overall this wouldn't really matter as Enel mainly wanted to flex and I'm not sure ALL the priests have "battle ready" mantra
(I could be wrong) so saying Wyper can overcome Deku's predictions seems a bit far-fetched for now, I am open to being wrong on that front though.
On top of that Deku likes to play "anime spiderman" ever since he got Blackwhip and float
(giving him better mobility), has mega-tough armor on his limbs, has Fa-jin as a BS amp, smokescreen does...something I guess and he's pretty skilled in his own right while having precog that
(while, again, not on the level of kenbun) IS a pretty good advantage, and that's STILL a relevant factor even assuming Wyper fought Mantra users.
Wyper is one mobile ***** as well and Reject Dial is one hell of a drug
(and it/Impact Dials are potentially great for nullyfying...let's say...a Fa-jin attack coming at Wyper) but given Deku's danger sense and mobility
(and iIrc Fa-jin can work as a speed boost too...and Deku always charges it mid-fight to have it ready at all times) he should be able to see "oh shit, I have no idea why but if I get hit I'm dead" and play keepaway with air pressure nonsense and Blackwhip, expecially since Wyper is only going to use Reject as a last resort IC.
(I might be exagerating but he sure as hell isn't opening with it...which, ironically enough, would be a lot more likely to work)
