First fight with new Shifuto ayy, let's go.
First off, debunking @Kick very quick on the One For All thing. This version of Deku could control One For All, but it's much weaker than 100% (Since this is 5-7%), which is why he's 9-A in this version.
As for the fight itself, I'm actually leaning towards inconclusive. At face value, you'd think Shifuto would win, as he has more abilities (Electricity Manipulation, Pseudo-Flight, Shockwave Generation (Deku doesn't have this ability in 5-7%), and Regenerationn). However, Deku has faced enemies that were above, if not far above him, and still came out on top through his sheer intellect and stamina, which he has the advantage in both. Shifuto may have the ability advantage, but Deku, always having a clear an analytical mind, even in fights, will find a way past Shifuto's abilities.
In summary, inconclusive since it's hax (which isn't that much) vs intelligence and stamina.
Also question: This would also depend on whether Shifuto has Xi force, or just his Regenerationn here. If he does, then Shifuto would eventually fall because he doesn't have Regenerationn. However if he does, then the question will be how fast can he regenerate? If he can regenerate super quickly, then he'll eventually win through that alone. However if it's slow enough to be overwhelmed, then I'm keeping my inconclusive for reasons I already stated above.
