Which is better STAB or super effective (not 4x)?

Question

Hide this if it has broken the rules,please.

Answer 1

Why super effective of course. STAB gives a boost of x1.5, while exploiting a weakness gives you a x2 damage multiplier.

Comments

Plus, if they are combined it is x3! And of course, a double weakness is x4 on its own so all together you can get up to x6!!

Answer 2

Super effective is better. STAB does 1.5x damage and Super effective does 2x damage.
