I almost exclusively use self checkout unless there's a compelling reason to avoid it. I bet I only use the regular line twice a year, if it's even that often. I like bagging my stuff the way I want it. I organize it for easy unpacking when I get home. I put all my fridge stuff together, bag the things that are for future use together to put it in storage, etc. The only one I dislike is Kroger's, and that's because I use the coupons they send me. When you use a coupon at Kroger, the computer stops until the Self Checkout Monitor Person (SCMP) takes your coupons from your hands and then unpauses the computer so you can continue on to the Payment part. The computer verifies that you've scanned the proper items so as to qualify for the discount, and I guess the SCMP takes the coupons so you don't use them again and again. So there can be a delay as you wait for the SCMP to come over.
