My very first thought before reading who it was, was "Oh, that looks like William", then when it was revealed to be Dante, I thought "Yeah, I can totally see that too." They did a good job I think.
Ok, here is a needlessly in-depth response because else i would have to actually work in the home office:
It´s the hair. White man + half-ponytail always looks like Geralt at first glance, that was already a "Problem" with William or Samurai-Geralt, as true fans call him i heard.
Don´t know why, probably because TW3 was so popular and the hairstyle became kinda Geralts "thing", it even invaded the Netflix Series.
NiOh2 really doesn´t have much options for mens´ hair either, its either tied into a knot/ponytail or you get that DQ11 Hero-Hair :/ Longer white hair + white dude = instant Sephiroth (or Elric, depending on whether you were bullied at school because you read fantasy books or played Videogames).
Going by the actual faces, they all look markedly different though. Here are some Pictures i spent 15 Minutes searching because that was a good reason to postpone our daily zoom-meeting at least for a bit.
Geralt (notice the indifference mixed with a dash of Sadness and self-loathing. Classic!):
William (Dat Chin!!)
Dante (the only one with an actual, 3D-scanned human face!):
