Destoroyah takes this pretty handily. Showa King Ghidorah wasn't all that impressive except in Destroy All Monsters. Destoroyah is bigger, more durable, and arguably more brutal.

Destoroyah survived multiple hits from Meltdown Godzilla's spiral ray while King Ghidorah was maimed by Showa Godzilla's much weaker atomic breath. Based on what was discovered in another thread, Showa Godzilla's atomic breath has a temperature of 100,000 degrees C based on what was recently while the red spiral ray is more than 10 times hotter.

Destoroyah's micro-oxygen beams also seem to be more damaging than King Ghidorah's gravity bolts, his horn katana nearly slicing clean through Godzilla, and Destoroyah can absorb energy by injecting micro-oxygen into his opponent on top of that. Destoroyah is all-around more powerful than Showa King Ghidorah. Even if the two monsters were scaled to the same size, Destoroyah would still win.

Destoroyah is likely more powerful than any incarnation of King Ghidorah with Rebirth of Mothra 3 King Ghidorah being the only possible exception.
