Can we say this:

1) Nico depends more on his powers than on his fighting skills, and his reliance on powers is increasing, even as his skill is growing.

2) Piper is learning to rely less and less on her powers and more and more on her fighting skills.

Hence, Piper might surpass Nico eventually. But right now, Nico still has much more experience (two more years, Underworld, Tartarus, Titan War, etc.), and hence, more skill.

[Tartarus reminds me: how was Piper able to fight Mimas better than a Tartarus veteran (Annabeth)?]
