Costco Vs. Sam's Club!!

Hi moms...I have a Sams membership...but thinking of going to Costco.. its just easier to get to. Just wondering what my moms think :) I usually only get like paper towel, toliet paper, water at Sams...those are the MAIN things. Also, is Costco like sams in that you only pay onec a year?? Thanks :)
