That's somewhat subjective. Situationally, each one can be worse in its own way and neither is conclusively worse, as in, there's no situation you can name where I can't think of something worse from the other, and I've experienced both growing up in school.
This is not something we should try to say one is worse than the other, they're both terrible and need to be stopped, but as responding will never be as fact as reacting it's better to teach people to defend themselves. Again, I'm not saying we shouldn't act, but the chances of people who can intervene being present when someone is being abused is slim to none, and even if they're called, they can never act as fast as the target of abuse. If we can teach them to defend themselves, at least enough to escape, and not punish them for doing so (as often happens in schools nowadays) it will work far better for the future.
