Overall, I’d say the Sawyer bucket system is a smart thing to have. The Sawyer company has a well established reputation for quality products with verified specifications. You can buy the bucket system, assemble it, test it, then relax. Practically speaking, there aren’t expiration dates or replacement filters you have to worry about. The only downside is the storage room that two five gallon buckets take up. You get good, clean water with the Sawyer filter, and when it’s driven by gravity between buckets, you get a lot of it, which is good, because after a natural disaster, I don’t want to have to spend a lot of time and energy squeezing little plastic bags.
