Power over stats for moves?

Question

So I have a Flareon with a base Attack of 134 and a Sp.Attack of 94.

So let me make an example: If I have a special type move that has a power of 80 but I want to teach the flareon a move that is physical and has a power of 50.

Which move should I keep?

Answer 1

Since Flareon specializes in the Physical category with its high Attack stat, I'd give it a Physical Fire-type Attack. It can learn Fire Fang (65 power-95 accuracy), Flare Blitz (120 power-100 accuracy), and Flame Charge (50 power-100 accuracy).

Here is what you should know about these moves before you give them to your Flareon:

Fire Fang deals damage, has a 10% chance of burning the target and has a 10% chance of causing the target to flinch.
When a Pokémon is holding Firium Z and uses its Z-Power, Fire Fang turns into Inferno Overdrive and has base power 120.

Flare Blitz deals damage and has a 10% chance of burning the target, but the user receives 1⁄3 of the damage it inflicted in recoil. In other words, if the attack does 90 HP damage to the opponent, the user will lose 30 HP.
When a Pokémon is holding Firium Z and uses its Z-Power, Flare Blitz turns into Inferno Overdrive and has base power 190.

Flame Charge deals damage and raises the user's Speed by one stage.
When a Pokémon is holding Firium Z and uses its Z-Power, Flame Charge turns into Inferno Overdrive and has base power 100.

Answer 2

This is the damage formula.
damage=((2*level+2)/5+2*power*attack)/(50*defense)+2

The only things we're changing are the attack's base power and the used attack stat. It should be pretty safe to assume that, on average, stuff like defense stat and other modifiers stay the same. With that said:
what we care about=power*attack
One move's base power is 50, and it uses an attack stat of 134 to calculate damage, so its "what we care about" is 6700. The other move has 80 and uses an attack stat of 94, so its "what we care about" is 7520. Therefore, use the special attack, until you get a stronger attack like flare blitz or fire fang.

What about STAB (Same Type Attack Bonus)?

If both attacks get STAB, then it shouldn't matter.
