my best cans to date have been the old civilian non-CARB 5 gal Scepter gas can.
even though they're still made in canada, and the maker says they are sold in the USA, i can't find them anywhere of course.
new ones look like this:

none of the newer CARB cans & spouts that i've tried are worth using, so when i have to transfer fuel from a modern can, i just use a large flex-neck funnel that has a big bowl and wire it to the top of the pick-up bed to hold it in place while i pour without any spout on the can. (and being a pick-up, i simply stand in the bed and lean over the side to pour. way easier than standing on the ground, trying to hold the can at chest level!)
in the past i have used the siphon systems (shaker or bulb-&-valve), but damn, they're incredibly slow.
fyi - i did find some older flexible "w/ breather-tube" spouts to replace broken spouts on my Scepter cans. and they work almost as fast as the plain-old hard-tube type that came with each can. but due to changes in dimensions (due to CARB regs???), they don't fit newer cans of any make.
