I think it's too early to judge mate; we're not even at the half of the year. However, if I would base my answer on what's happened already, I would say Bitcoin has been better this year compared to Ethereum, at least for the past few months. I say that because Bitcoin has shown way better movements, specifically increases in the past several months compared to Ethereum, which mostly showed only dumps with gains, but were not too significant so-to-speak.
