I like that it's easy enough anyone can use this without having any technical knowledge of how caching works or what rediss does best! We've been able get some pretty good results using wpcacheto speed up our site by about 50%. It has helped us reduce page load time significantly since we started running tests before deploying new features/code changes as well which helps me sleep at night knowing my code isn't going live until its ready :) There are no downsides either so far when i have used other services out there they tend towards being too complicated (which was why google did not pick them) but you dont need much experience if your willingto learn once setup correctly - just make sure all caches setuptools match otherwise things will break down quickly!!
