Common / Useful Design Metrics for Aircraft Comparison?

When watching Barnaby Wainfan's videos, he brings up the concept of transportation efficiency (useful payload / Gross weight * Lift/Drag) as a metric to compare aircraft. I wonder what other metrics are used to evaluate different designs. Pure Lift to Drag is a common one as well. I've also seen from Torenbeek's Advanced Aircraft Design Mach # * L/D as a metric.

Are there other ones that are typically used?

Thanks!
