I have a foodsaver, one that came with a sous vide machine, and a vacuvita. I like the foodsaver best. The only thing I like about the vacuvita is that you can open the bags, and reseal them, like a zip lock. It's huge, and you are supposed to leave it on your counter and keep bread in there. It does an amazing job at the bread, but I don't eat much bread. I also like the containers, but I'm not sure how much difference they make in my lifestyle.
I think vacuum sealing is great, but wish I could afford the "chamber" kind that is used in restaurants and can handle liquids.
