I would say it depends on location, give percy any source of water (he is willing to use as he is not inclinned to use water in plants or animals) and he would win, though jason has an advantage of salt water conducting electricity but i still think percy would win overall many of their wind powers cross over, if percy had no water source though i think nico would win

I wonder whether percy will be able to use rain as a power source as he does with still water, and can nico manipulate black flames

I think nico would beat jason, jason can strike with lightning quickly but nicos shadow travelling would help with that, he also tends to just appear around people alot, if he can manipulate the earth as seen before when sealing kronos off in the labyrinth and banishing skeletons he would have the advantage of protection through lightning using black earth walls

Jason is also an inferior fighter too percy, percy was trained by luke who was considered one of the greatest fighters and whose skill was maintained even when kronos possessed him so he must have deemed the skill worthy, as jester stated percy defeated the war god and stood fairly well against Atlas the greatest titan warrior, jason did defeat a titan but that titan constantly complains about being weak and never given anything important or powerful to be incharge of,
