What is stronger - Super Saiyan 4 or Super Saiyan Blue?
Heres the truth: SS4 doesnt stand a chance against SSB. In the first 10 or so episodes of DB Super, Goku becomes a god temporarily and fights Beerus 1 on 1. Of course Beerus isnt even using 10% of his power, but thats besides the point. Goku and Beeruss battle is so intense planets are in danger of exploding across the galaxy. The first clash with their fists sends a shockwave that travels far across the galaxy from earth, reaching even the planet of the Kais. By Elder Kais estimate, after 3 clashes its possible the universe could be destroyed. The only reason this doesnt happen is because Goku adapts and figures out a way to nullify the effects, so the shockwaves stop completely. Why is this important? Because Goku as SSG was even weaker than he is as a SSB. With that in mind - its clear which form is more powerful. SSG would destroy SS4 based on the facts. SSB is so much stronger, Goku could literally snap his fingers and SS4 Goku would be in cardiac arrest. Remember what happened when Beerus flicked Goku in their first fight, and how Goku was gasping for life not long after? Thats the difference between SSB and SS4. Not even Omega Shenron was that powerful.
