What move is better giga drain or razor leaf?

Giga Drain is generally considered better than Razor Leaf because it not only deals damage but also heals the user for half the damage dealt, providing sustainability in battles. Razor Leaf, while having a higher critical hit ratio, does not offer any healing benefits. Additionally, Giga Drain is a special move, making it more effective against Pokémon with lower Special Defense. Overall, Giga Drain's utility and healing make it the preferred choice in many situations.
