Archangel's (and therefore Seraph's) has several key advantages. The first is that it grants more AP even if you have no stacks (unless you're a manaless champ.) The second is that the shield protects you from an obscene amount of damage (effective health) without making you more susceptible to %health damage.

Both does work sometimes, but you'll often be getting too much health at the expense of not enough resists. Good if the enemy has little-to-no HP shredding, but otherwise, you're often better off just going with one and filling out with Rylai's, Liandry's and resist items (frozen heart is good for Seraph's as a resist item).
