not really, it would be better than both of them
Arcanine can choose between Flash Fire (being an actual Ninetales offensive switch in on RU, for example) or Intimidate. It's speed, bulk, and power is very similar to Entei's, while having superior coverage movepool compared to it, boasting Close Combat and Wild Charge to beat Rock- and Water-type resists. Not having those juicy Sacred Fire Burns isn't cool, but the extra coverage is definitely worth it. On top of it, Arcanine can do almost the same as Incineroar while having recovery (though not having U-turn or Knock Off hurts a bit) and can even be a cleaner with Agility.
tldr arcanine is broken
