In a pinch, Praxis is the best choice for mining if you can’t be bothered to train astrogeology V and other fluff skills on a combat pilot.
Venture isn’t even close in output, even with perfect skills, and Endurance needs even more skills.
Also it’s the best choice for alpha, skill-wise.
Used 2 Praxi to get Extended boosters on the last event from alpha accounts, was pretty quick.
