Sword fighting i would definetly give you but percy has not learnt earthquake abilities yet apart from accidentally destroying mount st helens and he required a resivour to make a small huricane,

nico can effect the earth aswell such as sealing off kronos when he first possessed luke and he split the earth apart to banish skeletons, if parents powers are inherited it is likely nico may have or develop ability to manipulate black flames or possible even hasten death both of which would make him certainly even the scales without a prime water source,

percy and nico debateble but i would say percy > jason and  nico > jason
