If so, why?

In a couple of cases I have seen the Igloo as much as $60-$70 less than the Coleman.

Also have noticed that in pics the Igloo has latches on the lid and the Coleman does not except on the split lid model. Did not know if this was a big factor or not.

Latches good or latches bad?

I didn't shop diligently online... I went to the store and the Coleman was cheaper at the store...

I didn't know igloo used a plastic with less odor.... that's a good selling point... and if the igloo is that much cheaper it should be an easy decision...

You could put weatherstripping around it(on the inside!!!!)as another layer but I just looked at them in the store and found one that fit better than the others.

These were the best price, the main reason I got the ones I did, value for dollar, and as I upgrade, they will be great coolers still to use for whatever.

The latches are the first thing to break.

Giddy up cowboy. I've got 3 at 100qt plus, 1 Coleman, 2 Igloo, good seals on all.

And they're superfluous unless you're riding it around in your truck.🇨🇮

Currently using two of the same and they do a great job. I'm pretty much out of space and just exploring my options. The 150 on it's end should not have any larger foot print than the stacked 48's. Thinking I would like the vertical storage over the current cooler shuffle.
