Outrage
Earthquake
Dragon Claw
Stone Edge/Toxic/Sleep Talk

This Moveset lets Garchomp become arguably the best revenge killer. Its amazing Attack and Speed along with two great STAB moves in Outrage and Earthquake lets Garchomp destroy almost anything. Dragon Claw provides a more reliable STAB move and Stone Edge gets good type coverage. Toxic can be used to cripple some threats and Sleep Talk allows you to switch in to sleep moves with ease.

Outrage
Earthquake
Stone Edge
Dragon Claw

Even without a speed boost Garchomp still has amazing speed and now even more attaching power. Outrage and Earthquake are only resisted by two Pokemon, Bronzong and Skarmory, so a Fire move, Such as Fire Fang, can be used instead of Stone Edge. Dragon Claw lets you get a STAB move with out being locked in to Outrage.

Swords Dance-Jolly Nature-Life Orb/Yache Berry
Swords Dance
Outrage/Dragon Claw
Earthquake
Stone Edge

With Sword Dance and Life Orb Garchomp becomes almost unstoppable. The three attacking moves are only resisted by Bronzong. Outrage is a much stronger option, but Dragon Claw prevents you from becoming locked on.
