"Most powerful" is very subjective, different variation from different schools/styles work very differently. Like Yunan's 情蛊 will kill you if you betray the caster, that's powerful but doesn't change your feels, some variations use illusions to control your mind, but you will slowly  be driven insane. Others control you with lust but those usually fall apart when you start to 精尽人亡.    The best is still to improve your 姻缘 by improving your merits, it's the toughest path but the most stable.
