"Best" is not a the best choice of words in this case, very much depends of what are your "wishes". (try googling "thermoelectric generators for deep space exploration" for a fun different application of what's best in nuclear fission energy recovery)
This said as pointed out previously , steam turbines have an efficiency going from 60% for small systems all the way ip over 90% for big turbines, the kind you might expect from a huge reactor. So, up to date, steam engines are the most efficient for domestic energy production
