She values different things than Fleur.

However: I think she'll have more respect for Fleur now that she's seen her loyalty (to Bill). Which won't make her like her, but she might dislike her less.
I went to look on hp-lexicon and saw that (as odd as it may seem) Tonks just happened to be in Hufflepuff. I would have gone for Gryffindor or Ravenclaw to, but I guess it was neither.
