I've got Yeti, Igloo, Coleman and some no name knock off coolers. If you are just using them as everyday beer coolers, there's not a nickels worth of difference. If you're using them to pack and transport frozen meat or fish the Yeti wins hands down. The other brands of roto-molded coolers may work equally as well, I have no first hand knowledge.
Point being, you have to use the right tools for the job at hand. Coolers, firearms or wrenches, some are fine for casual use and others are more suited to serious applications. YMMV
RTIC hasn’t let me down.
