Neither. I would like there however to be a credible power to challenge U.S. policy, perhaps China even, so that it's hard for both sides to get aggressive policies implemented internationally as there's credible pushback.
Right now, there's practically no pushback on crippling U.S. sanctions against Iran or Venezuela for example.
I have yet to see recent news of them bombing other countries, kidnapping people from around the world and destabilising regions around the world.
In truth, I'd rather have neither of them bullying others but if I had to choose, I think the less violent bully is a better choice.
