Those scepter/jerry can style containers look the part but they seem to me like they'd be a PITA in real life to use - at least unless you buy a separate valve for them and then you're pretty much right back to the coleman design but with something that isn't as stable on it's side.
Personally, I've used a coleman 5 gal for years with no problem, though I do turn it up unless I'm using it. I just bought the Reliance version, which is 7 gal and BPA free, so I'll use that for drinking water and relegate the coleman to cleanup duty. Haven't tried it yet, so I can't comment on the quality, but it looks O.K. They make several different types - stackable, collapsable, jerry can, etc. - they all seem reasonably priced.
