I bought the smaller jug because I am 70 years old and it is a lot easier to get in and out of the bed of my truck to use for my lawnmower and other things. It’s perfect and I love the color pink.

Despite being "high performance" the storage nozzle cap still leaks with these o-rings. The other o-rings in the set are leak free though.
