Gourry Gabriev vs. Kazuma Kuwabara

Two dunderheads that wield swords with blades composed of energy.
Battle takes place in a parking lot after a Megallica concert. Who wins this?

Depends on when.

Gourry is more skilled (he's crazy good), but later on in YYH Kuwabara is way more powerful as Gourry doesn't get shounen fight power ups to speed and strength.

Early Kuwabara, Gourry'll slice him up, late, he wins on shear power.
