Flaeron VS Arcanine

Attack...Overheat Flareon
Defence...Arcanine for the bulk

I like both for attacking, but more Flareon just because of more powerful attack(Overheat)
Defense clearly Arcanine because Flareon is so fragile.

I prefer Charizard w/ overheat for attacking, but for sure Arcanine for defense. He's more tanky than the other fire-types. Flareon is probably a better attacker than Arcanine if you get overheat.

While Flareon might do more damage on attack he is a bit too glass cannon for me and is very susceptible to take big damage on his charge moves.

I have a 96% FF/FT Arcanine at 2723CP and absolutely love him. He's tankier than Flareon and can actually survive a few shots.

He does a ton of damage and can also be used on defense. He is my go to guy.

Arcanine more dodge forgiving
