Subaru Crosstrek battery - Costco vs Subaru vs Other

Hey guys, I’m approaching four years with my 2021 Subaru Crosstrek Outdoor, which means I’ll soon need to replace the battery. I’ve been checking Costco’s website and feel that a Kirkland battery is a better option than getting one from a Subaru dealership due to its lower cost and better warranty.

What did you do in the past and how has your experience been?
