I guess going into details and thinking of something specific to give original Dante to not spite against the newbie is something that's too much to ask for. Let me guess, New Dante only automatically loses 'cause nobody likes the "Nicholas Hoult look alike with the personality of a TF2 Scout." Is that the reason?
Here's a lightning speed feat for dante

they reacted so fast that the lightning is taking time to fade meaning their response time is in the microsecond range
Dante can physically match the Hunter, who was able to push a thousand ton ferris wheel, that and uppercutting Mundas.
DT Dante w/Eryx can punch Mundas some distance and knock him out which is a step up.
That makes new Dante a supersonic (Mach 1) building buster in base, and a hypersonic (Roughly a 1/1,000th speed time lag + speed boost.. appears to be Mach 1,000+) large-building buster in DT mode w/demon weapons.
He's physically stronger and slower than DMC3 Dante. Less hax too.
no problem.
and true that. hell, not even Drekavac (the dreamrunner with the red face) could get Dante to take him seriously and from what is said, he's supposed to be the strongest dreamrunner. hell, even gameplaywise, Drekavac had more health than other dreamrunners and seemed a bit smarter and stronger too. guess, DmC Dante is faster than expected.
