Head Smash or Rock Wrecker?

Question

Both have the same power, so which should I go with?

Comments

Rock Wrecker is a move that can only be learned by 4 Pokemon, so I'm presuming your Pokemon is Crustle or Rhpierior. But further research says that **NO** Pokemon can learn both moves
[Rock Wrecker][1]
[Head Smash][2]
Well if you want a description on a Smeargle or something
XD

Answer 1

Out of the two given options, Head Smash is better in a competitive scenario

Let's take a look at both;
Head Smash - 150 Power, 80 Accuracy, recoil is 50% of the damage you dealt.
Rock Wrecker - 150 Power, 90 Accuracy, recharge turn.

So why would I support Head Smash?
As a general rule, moves that force you to recharge (Hyper Beam, Blast Burn, Frenzy Plant etc.) are not viable in a competitive scenario. It means you lose momentum on that recharge turn, and furthermore potentially give your opponent a free turn to set up, allowing them to possibly sweep through your team. While Head Smash vasly reduces the longevity of your own Pokemon it gives your opponent less chances to sweep through your overall team compared to Rock Wrecker.

If this is in-game, choose Rock Wrecker. In-game allows you to change Pokemon provided you KO them, so using Rock Wrecker as a finisher is fine, as you can switch out with no repercussions due to the in-game battling system.

However if you have a choice, use Stone Edge or Rock Slide. While both are weaker, they lack the bad side effects from Rock Wrecker and Head Smash

Please note that no Pokemon can learn Rock Wrecker and Head Smash, so this answer is hypothetical and has no real bearing
