Butterfree is better but if you train oddish it will evolve to gloom then use a sun stone or leaf stone to evolve it to vileplume/bellossom which are a little better than butterfree but butterfree can learn psychic type moves which can defeat vileplume and bellossom so choose butterfree if you want that but if you want an offensive and defensive Pokemon choose vileplume.
