Wankel engines are great in one respect, power density. But they have terrible reliability and fuel efficiency.
Turbine engines also have great power density and terrible fuel efficiency, but they are very reliable.
Diesel engines are reliable and fuel efficient but heavy.
This one appears to have improved reliability and fuel efficiency over the Wankel without sacrificing power density.

Turbines are bad at scaling down to smaller sizes due to e.g. boundary layer friction, and also part load efficiency is poor. Recuperators help somewhat, though still not nearly as good as a piston engine.
