BG1's "Finally! A Match-Up Worth Seeing" Edges:

Note: Despite having not played Mass Effect and played the first 2 Halo games, I am not generally biased to a character so... here goes nothing

Bladed Melee: The Energy Sword is perhaps the longer of the two weapons but a key difference is that Chief can be disarmed from the sword whereas Shepard cannot be as easily disarmed from the Omni-Blade. Also, like you point out, the Omni-Blade has that element of surprise that MC might not suspect and the Energy Sword is useless once the energy in it is wasted outED

EDGE: Shepard

H2H: Master Chief gets the edge here - he has gone through rigorous training that will have involve martial arts on a heavy basis, plus his suit enhances his physical capabilities to superhuman levels meaning he will have the strength to pummel Shepard into a pulp or at least bruise him very badly

EDGE: Chief

Pistols: You've already stated what could be said about the pistols - the M6H has a good range and accuracy but the M3 has more rounds and a higher RoF. As Bull also points out in his vote, the M3 has inferior bullets than the M6H but to me a higher concentration of inferior bullets gives the same amount of damage as a lower concentration of powerful bullets and given the M3's mag size and RoF the two do pretty much the same amount of damage. But since the M6H has accuracy and range...

EDGE: Chief

Shotgun: The Katana loses out in terms of mag capacity but since it is semi-automatic compared to the pump-action of the Tactical Shotgun, I think Shepard will be able to dish out more damage more quickly than Chief - even if the Katana is horrid at long range

EDGE: Shepard

SMG: MC is carrying two SMGs compared to Shepard's one meaning MC has the edge in ammo capacity and damage output but loses out in accuracy and looking at the stats, even RoF

EDGE: Even

Assault Rifles: *copies SPW's edge* (sorry :P )

EDGE: Shepard
