It also doesn't help that Buffy's group and SG-1 are roughly parallel in makeup, but Buffy's group has more 'extra abilities' (albeit also worse internal dynamics), so if it comes down to which group is going to suffer from an Out of Context problem SG-1 is the easy choice.
That said all the better Buffy/SGC crosses I've seen have both sides dealing well with each other.
