Compressor couplings

What is the difference between "V" and "M" style couplings.
Which is best and why?
Northern tool carries their brand and "Milton" does it matter?
Thanks

V-style flows more air.

Thank you for a great demonstration.

I use the V style so that I can swap tools between work and home...plus it prevents most people from trying to use my tools.
