Fire Punch or Steel Wing for my Flygon?

Question

With the release of ORAS, I can now get tutor moves! :D
But here's the thing. Last time everyone told me to go for Fire Punch over Steel Wing, but Steel Wing has caused me some great success.
Current set:
Item: Life Orb
EVs: 252 Atk/252 Spd/4 Hp
Jolly Nature
-Steel Wing/Fire Punch
-Earthquake
-Superpower
-Dragon Claw
Which one?

Who is the rest of your team, and what are their movesets?

Funny, i just recently i had to make the same decision with my Flygon XD

Maybe get rid of Superpower and teach it both moves! :D

Answer 1

I'd say Steel Wing. It covers both its Ice and Fairy weakness, while Fire Punch only covers its Ice weakness. I believe that Steel Wing has a chance to raise defense too which is pretty useful.

Steel Wing covers 3 types while Fire Punch covers more.
Need more info

Steel Wing is good as it covers 2 of his weaknesses and has a chance of raising Defence, but the chance is only 10%. Fire Punch only covers one of its weakness, but can hit more Pokémon super effectively (better coverage?). Fire Punch has the same 10% chance of burning the opponent.
