Haku can turn Water into ice in both Manga and anime, it's part if the Whole demonic Water mirror gig, the question is whether or not Haku can turn Water that's saturated with another persons' chakra into ice. If yes, Suigetsu is beaten hands down. If not, then the battle might be long and hard but I think Haku'd win in the end.

Haku's both faster and smarter, he'll figure a way around Suigetsu's defences and knock him dead.

(Plus, as a side note, it says on Haku's page that Zabuza trained him in every figthing technique he knew, therefore it could be argued that Haku has access to all of Zabuza's techniques as well, giving him a vast arsenal that's more than enough to smother Suigetsu. (I admit this might not be a strong argument, because I don't know if those are Kishimoto's own words about Haku's background or an editor that was being creative with the description))
