I'm both a Pein/Nagato and Itachi enthiusiast.
But I'm going with Pein on this one, due to the fact that Itachi cannot sustain MS for long enough, nor keep the insane Rinnegan techniques in check.
As well as this, even if he miraculously defeats the Six Paths, how is he going to find Nagato? And even then, Nagato will probably fire his nail and control Itachi FTW, since Itachi would probably be near-death at that point to evade it... also Nagato has his bi$%& to protect him as well.
And there's the matter of Itachi getting sucked into Chibaku Tensei if it even gets to that point...
"Before overwhelming power, all is meaningless". Period.
