According to my layman's understanding and Issac Arthur's science and futurism videos, fusion is great because of how universally common the fuel is. Maybe fission fuels are not a big deal on Earth, but they are on the moon, Mars, orbital habs or Europa. Meanwhile fusion is just hydrogen. Literally what's the universe is mostly made of. So maybe right know fission is as good as fusion (better because it exists), but space is soon, and fusion is better for space.
