I mix up a gallon in an old shampoo jug. I use less than two quarts for most washes (I fill both foamguns but seldom empty either of them). *For the way I wash* I prefer the smaller bottle, less likely that I'll bump the car with it when doing the horizontal surfaces (manipulating the smaller bottle version is hard enough). But note that I often have the nozzle of the foamgun either in a mitt (mitt-balloon technique) or tucked into the bristles of a BHB; with a more normal foamgun technique I dunno if there'd be any problem with the larger bottle.

I use Griot's Car Wash. The mix in the foamgun's refill jug *is* stronger than a regular wash bucket's mix, but remember that the foamgun dilutes it further. BTW, I use the sorta-strong mix for the foamgun to clean my wheels/wheelwells too. I'm none too scientific/precise about mixing shampoo; if it's too strong/weak for the foamgun I adjust it at the gun, if it's too strong/weak in the wash bucket I add more water or shampoo. After using the same shampoo (and the same pump dispenser) for years, I just do it by eye, pretty much on auto-pilot.
