One is ready now. The other only works if you have warning.
Verdict
Stored containers are full before anything happens, which is the point, and they take up space permanently. A bathtub bladder holds a lot for very little money and storage space, but only helps if you have warning and clean water still flowing. Store containers as your baseline; keep a bladder for hurricane and storm warnings where you get notice.

One gallon per person per day is the common planning figure, covering drinking and basic hygiene, with two weeks a sensible target. Pets need their own allowance and people often forget them.
Commercially sealed water keeps for years. Water you bottle yourself in clean food-grade containers is usually rotated every six to twelve months. Store it cool and out of sunlight.
Often yes, and it is a substantial reserve most people forget. Turn off the power or gas to the tank first, and draw from the drain valve rather than the taps.
