I love out Yeti. We have had it for almost 10 years and its been great.
We did two weeks in Baja racing with a cooler that Pelican sent us to test. While I love pelican, I though the overall outer dimensions where massive, compared to the internal volume -- mostly because it has these big, built in molded handles unlike the rope handles of the yeti.
I also find the Yeti to be pretty indestructible. We did accidentally plow into the Pelican with the Race Truck during a pit stop. It ended being just find, but the plastic seems to scratch & gouge much easier than my yeti.
