Which move would be better on a Mega Metagross?

Question

Iron Head or Meteor Mash?
Meteor Mash has more power and a 20% chance to raise attack, but has the tiny chance to miss which no one can afford and can cost them the game.
Iron Head has 10 less base power but more accuracy and can save someone with that 30% to flinch which is good enough.
So which one is better on a Mega Metagross?
Alo suggest pros and cons please.

Doesn't Meteor Mash have a chance of raising your attack?

Answer 1

Meteor Mash
Pros:
1) Has an amazing 90 base power.
2) 20% chance to increase attack by 1 stage which would give the move an even greater power!

Cons:
1)90 accuracy means it has a little chance of missing,which could be a problem in some stages of the game.

Iron Head
Pros:
1)Has a 30 % chance to flinch the opponent.
2) Has a higher accuracy than Meteor Mash

Cons:
1) Has less power than Meteor Mash,which could prove to be crucial
2)It can only flinch if the opponent has not moves yet.Meaning it would not flinch opponents that are faster than Mega Metagross.
3) Cannot flinch Pokemon behind a substitute or Pokemon with inner focus.

I would go with Meteor Mash here because of the power and the chance to increase attack,despite the lack of accuracy.If you are worried about the accuracy,have a another move that has 100% accuracy so that you can use it on the crucial stages.

Hope I helped!

Answer 2

Assuming that this is for Mega Metagross:

• Meteor Mash after STAB and Tough Claws clocks in at 175.5 damage
• However, its tendency to miss, unlike Iron Head, will throw off a game much more than any power difference
• Iron Head comes in at a power of 156 after the boosts, significantly lower than the power of Meteor Mash

The difference in power and accuracy can be calculated into one number using mathematics. Since missing an attack gives a move a power of “0”, and Meteor Mash has a 10% chance of missing, it’s average power is 157.95; barely any higher than the power of iron head.

Taking both Meteor Mash’s chance to raise power and Iron Head’s chance to flinch, my personal decision is...

IRON HEAD. Having nearly a 1/3 chance to flinch another’s Pokemon is an invaluable asset in battle; this gives your opponent a 30% chance to miss in which Meteor Mash makes YOU miss. A power boost is pretty nice, but both swords dance and bulk up can do that, especially on a baton pass Pokemon. 30% is a plenty high number to flinch, and can easily change the tide of the battle in your favor.
