80% ATK boost isn't much, since it contributes less to the overall damage when it is additively added to the raw ATK stat. Elemental weakness is a multiplier and can affect the final dmg more than the ATK stat if you already have other sources of ATK boost such as LS, sphere, ES.

Krantz' Elemental weakness makes the weakness multiplier 2x on the right elements and also guarantees at least neutral damage (instead of dmg being cut by half against a stronger element), so even in terms of dmg krantz is more useful universally.

But more generally, krantz has more utilities w/ his BB and SBB, while shera just has an ATK buff, which is easily replaceable (80% boost is really bad...and has risk of overwriting better buffs).
