Verdict
Winner: Mega Lucario (1v1) / Garchomp (team utility)
Mega Lucario wins 1v1 with Adaptability + Speed. Garchomp wins as a team backbone.
Context: why this matchup matters
Lucario (Gen 4, Sinnoh) and Garchomp (Gen 4, Sinnoh) are both signature Sinnoh Pokémon — Lucario was Riley's ace, Garchomp was Cynthia's ace. Both became iconic competitive picks. Both got Mega Evolutions in Gen 6. They represent very different competitive archetypes (Lucario = mixed glass cannon; Garchomp = bulky physical attacker).
Stat battle: who has the numbers?
Lucario: 70/110/70/115/70/90 BST 525. Mixed attacker with 115 SpA. Garchomp: 108/130/95/80/85/102 BST 600. Physical attacker with 95 Def + 108 HP making it bulky.
Mega Lucario (625 BST: 70/145/88/140/70/112) becomes Adaptability — STAB attacks 2× damage instead of 1.5×. Mega Garchomp (700 BST: 108/170/115/120/95/92) gains huge SpA at the cost of Speed — turns into a mixed wallbreaker.
Mega Lucario's Adaptability ability + 140 SpA = Aura Sphere becomes essentially a 180 BP nuke (140 SpA × 2× STAB = effectively 200% damage modifier).

Bullet Punch priority: Mega Lucario has Adaptability Bullet Punch (Steel STAB priority) which OHKOes faster glass-cannon Mega Lucarios in mirror.

When to pick each
Pick Lucario for: Mega Lucario Adaptability special wallbreaker, Swords Dance + Bullet Punch priority sweeper, Aura Sphere spam (Fighting STAB hits Steel + Dark + Normal). Mega Lucario is one of the strongest Mega Evolutions ever released — banned from Smogon OU temporarily after release.
Pick Garchomp for: Stealth Rock + Scale Shot sweeper (Loaded Dice abuse), Sand Veil dodge mind games, Sub + Dragon Claw setup, defensive Rocky Helmet pivot. Garchomp's bulk + flexibility make it the most-used Dragon-type in OU history.
