So cold fusion (as in cold enough to run on Earth, not cold enough to power your laptop) may compete with it, depending on what it will end up being. Unlike fission, fusion requires very specific parameters and if those are not present the reaction stops. My understanding and memory of this subject is rather dim, but I remember discussion benefits of fusion over fission as a potential power source in college.

Cold fusion is totally the wrong term here, no matter how you twist it.

Artificial fusion actually requires higher temperatures than fusion in the core of the sun[1] because other parameters are less beneficial than at the center of the sun.
