You can buy a lot of ice for the price of a Yeti, but sometimes buying ice is not an option, or you cannot make ice. While I think the Yeti is overpriced, it definitely does the job better than anything I have ever owned. It's kind of like buying tools, you can burn up two or three cheap Black and Decker Drills for the same price as one good Dewalt drill, but when you need a drill, you don't need to worry about it working. Same with a Yeti, the price is crazy, but it works and you don't have to worry about it. I have looked at Orca's and Pelicans I think they probably would do a good job as well.
The thing that drew me to a Yeti was the overall construction. I can't tell you how many coolers over the years I have thrown away because the hinge or handles broke, a corner got cracked, it smelled too bad from fish, or the lid couldn't handle my big rear. My Yeti has taken an absolute beating from work, hunting, fishing, camping and it hardly has a scratch. It even fell out of the back of my truck and hit the pavement, didn't even spill a drop of water.
