It would definately depend on the situation.  When we watch cheetah hunt, we=
 see that the gazelle usually runs.  However, there are a few instances=
 where the gazelle turns it's horns on the cheetah.  I suspect that the=
 temperment and armament of the herbivore would have to be taken into=
 account, but here's my thoughts (I'll ignore groups that I don't know very=
 well):=20

>1) Ceratopians?
-Small genera would usually use flight, while the larger would choose fight.

>2) Hadrosaurs?
-Flight mostly

>3) Hypsilophodontids?
-Ditto

>5) Iguanodonts?
-Mixture.

>7) Diplodocids?
-Mixed.

>8) Brachiosaurs?
-Mixed.

>9) Pachycephalosaurs?
-Fight occasionally, flight otherwise.

>11) Heterodontosaurs?
-Fight.

>12) Ankylosaurs/Nodosaurs?
-Fight.

>13) Stegosaurs?
-Fight.

>14) Ornithomimosaurs?
-Flight.

>15) Plateosaurs?
-Flight.
