To each his own.
I’ve found them to be the best fuel can for my purposes. The venting is back through the spout once they start pouring. No glug or spilling.
Sounds like you are looking for an automotive Gerry can. The “V” jugs are what you want.
I am glad that you have found a solution that works for you.
I am perfectly happy with the vented plastic cans that I already have that are no longer available because of ridiculous regulations. I have a couple of the “Jerry can” style containers but prefer the shapes that are more stable in your trunk. I used to keep our airplane at an airport without fuel pumps and used a 38 gallon plastic tank out of an old van with a hand pump to fill it up. It is interesting to me that the new cans are so difficult to use for filling up a car or truck that has run out of gas when that used to be one of their primary reasons for existing.
