45 yeti vs 60 k2 help

[PUREBAY2200]

I got my yeti in 2008....... Haven't had to replace a single thing on it. It's has been abused!! Fell out the boat on road, fell down stairs, even caught it in fire( camp fire and somehow gass was spilled on it and a cigarette was laid on the yeti). It hold Ice and keeps contents extremely cold.
A friend of mine went snapper fishing in destin a few weeks go. He kept his fish on Ice b the yeti for 5 days. Sealed up and didn't open. When he got home and opened it the ice was still there and fish was good and cold! That's proof they work.
I have never used a K2. So I can't compare.
But yeti is my go to for keepin stuff cold.
