Well, what sort of riding do you want to do with the bike? More steady long distance and relaxed or fast and sporty? French is more upright with the handle bar about even with the saddle, Competitive goes more aggressive with a lower handle bar, and the Eddy fits somewhere in the middle. Personally I go for the French or Eddy styles because I like to ride distance at my own pace without a care in the world about my heart rate or watts.
