Sunday afternoon weather gave me the opportunity to do comparison flights with different props on my MP1, at my club flying field with nobody about for at least 1/2 mile. Great for self-isolation. 
I ran a Litchi Mission, with auto take-off, flight, land so no human intervention to cock things up.
Weather was sunny, dry, wind speed in table below.
Course included two straight sections angled to each other, with mix of wide and tight turns
Batteries where similiar age, number charges etc.
results here …
So if you want efficiency, stick with the standard DJI props.
Does this surprise anybody 
I’d welcome your comments and if you want more details of flights etc. just ask 
Cheers
