I think a lot of it depends on what kind of ice you put in it. Down here in FL, on almost every corner, you see one of those ice vending machines. You can get a ton of ice real fast and much cheaper from there...but...that ice sucks. We no longer use those machines for that reason. The ice from them is barely frozen (especially on a busy day), and it melts really fast. Traditional bagged ice is the way to go. The last time we used the machine ice, we had frozen foods in the cooler. 4 hours later, when we unpacked the cooler, the frozen foods were all thawed.
Another thing is that I think coolers like Yeti's really outperform standard cheaper coolers in really hot conditions. When you're dealing with consistent 90+ degree temps like we have here, they're still keeping ice when others can't keep up. Less than 80 degrees and there's probably not much difference between all the coolers.
IMHO, of course. And like I said before, those coolers are most definitely not worth what they cost. I wouldn't own one if it weren't for having gotten it for free. But yes, great cooler and superior construction. Plus, they send you a free bottle opener.
