There's nothing wrong with those, with one big exception: they aren't personal. One on one, depending on who it is, can allow a moment before and after the fight (or even during if they're sufficiently skilled) for them to communicate, to speak plainly with each other before they fight (assuming the villain isn't lying). With a team fight, chances are they won't be able to speak with the group as effectively as they would with just one person. Also, in a one on one fight, if it's with a villain the hero has been fighting for awhile, it'd give them much more closure if they fought them alone rather than with a group (assuming the hero is sentimental).
