You can't prove that Shepards armor cannot survive the blast of a power-bomb, as Shepard has not been hit by a power bomb, or that biotics will not affect Samus, as Samus has never had biotics used against her.

There's no correct answer to this, because one sides technology, armor and weapons haven't been tested against the other sides. For all you know, biotics could affect Samus, and all of Shepards tech could affect Samus, but there's no evidence on either side, unless you know the exact newtonic limit of Shepard and Samus' shields, the density and materials of each armor, the exact velocity, penetration and material of each sides rounds, I could go on, I really could...

So, how about we call it a stalemate until exact statistics can be brought forward, not in-game information, as this has been through a balance filter, and once each side has a full list of statistics and specifications, then we can TRULY judge which would win.

IMO, I'd go for Shepard, chances are that he has the more effective tech.
