The Costco lights are crap and I repeatedly see feit brand led failures. They are incredibly inconsistent in kelvin and output, have poor cri, and unless you get them on sale really aren't that great of a price. The Cree ls8 and ls4 offer high cri, great lumens per watt performance, and have extremely competitive dollars per lumen output.

You really need to pick your budget and lighting goals and go from there.
