The main argument against DD fusion is that about half of its energy output is high energy neutrons, which can only really be made use of by capturing them with another material and then using a boiler or something, whereas D-3He is 95% or so ionized and can be exploited with MHD generators or deflected with magnetic fields. However, for static power plants none of that matters much.
