What will be the most numerous type of fusion power plant in 2100?

Question

To count as a fusion power plant, the majority of the energy has to be derived from fusion and it has to output more power than it takes in.  If most of the fusion energy comes from D-T fusion, but some other reactions also take place, that counts as D-T.
