It's difficult to give you a good answer without knowing more of your stats (I'm also not overly familiar with ME), but I'd recommend keeping the old armour, and trying the new one for a few days. If you seem to be taking damage faster than you were before, then the difference in AC is not making up for the damage mitigation, so swap back.
