I don't have a problem with Snowing as a pair, per se, I have a problem that Snow. She still seems more like Mary Margaret than she seems like Snow. Charming seems to have found himself.. but I really don't like Mary Margaret as much as I liked Snow.
Alice remained clever and sharp witted with a clear purpose. Snow, it seems, was made dumb (to make the villains look 'better/more evil/more clever??') and she's never regained that season 1 wisdom, warmth, & charm. Of course, we only had Alice for one season, so who knows what she would have been like after 3 seasons.
