Ziplock is definitely one of the best when it comes to baggies and these Ziplock snack bags are great! Ziplock costs a little more when compared with other brands, but not that big of a difference. I have tried some cheaper bags and half the time I end up really disappointed in the quality and make of the bag. These are nice and strong. You don't have to worry about them tearing easily. They seal well and easily also. I really like the snack bags because of the size. I have kids in my house, so these are the perfect size for snacks on the go. They also are great if you are counting calories and want to portion things out into different bags. That helped me a lot! It's nice to know that I can just stick some baggies in my purse and if my kids get hungry (or me) I can just pull them out and hand them one. I also like to use these to sort out little things in my house and organize. I will definitely keep buying snack bags. I find them to be the perfect size!
