Hoothoot and Heracross are both not that good. Just use Eevee or Slowpoke.
By the way, if something outclasses another thing, that means something does another thing's job better. For example, Heracross and Fearow are both normal attack users. Fearow's normal attacks are stronger than Heracross's, so Fearow outclasses Heracross. Gengar doesn't outclass Heracross because they do different jobs.
