Which cooler is better?

I’m in the market for a cooler and I am trying to figure out if there is much difference between the 38 quart Igloo cooler that costs $25 and one that costs $35. The only difference I see of the bat is the more expensive one is heavier, so does that imply it will keep things cool longer?

It doesn’t have to be an Igloo, it is just what I have been looking at.
