Both cards are quite good. Let's compare, shall we?

Arcanine-Stage one, Ninetales-Stage one (tie)

Arcanine- 100 HP, Ninetales-80 HP (Arcanine)
Arcanine-3 retreat cost, Ninetales-1 retreat cost (Ninetales)
Arcanine-Flamethrower (1RR) (50) Discard 1 fire energy, Ninetales-Lure
(2) If your opponent has any benched Pokémon, choose one and switch it
with his or her active Pokémon (Ninetales)
Arcanine-Take Down (2RR) (80) Arcanine does 30 damage to self,
