I'm not sure who that is.
If Gaston is human but the Beast is not, then Gaston should win. However, Gaston sounds a tad boring and the Beast sounds more interesting.. or at least dangerous (as beasts are inclined to be).
I really have no idea. I could shapeshift into a beast and that makes the Beast a more suitable bed person?
Sean Connery at his current age or Roger Moore in his younger days?
