It also depends on where and how you drive, park etc.
To me, the difference between filling up on gas and 20 minutes on a Supercharger not only isn't enormous, but literally doesn't matter. But that's because I charge at home, usually drive only around the city and when I go on a trip where I need to supercharge, it's a few hours between chargers and by that time I need to take a ~20 mins break for coffee anyway.
If I had to use them to charge, yep, 20 mins would be enormous.
