I know that he wasnt a flawless person but i say Einstein

Albert Einstein

I'm a fanboy of early Einstein, especially when he took every opportunity to get criticism of his work.

Bohr was more of a QM guy, and I think there was some spat over this between the two.
In this context, I'm gonna side with my boy Bohr because he knew better about what's up at smol scales.

Who's smarter? Accomplished more? Who do I like better? Einstein seems to have gotten more mainstream press in life, so he's the only one I have much insight into... So let's just say 'not enough data to make a conclusion'
