Jetboil or backpacking stove and pot?

How much water do you plan to boil at each meal? The biggest difference between JetBoil and other backpacking stove+pot combos is the volume of the pot.

Backpacking meals on average take ~8oz of water per serving. If you're going solo, the 0.5L JetBoil is usually sufficient - that will boil about 16oz of water in one go so you have enough for a meal and a cup of tea.

If you're 2 people, a backpacking stove plus ~1L pot will allow you to boil enough water for 2 servings plus 2 cups of tea/coffee in one go. Or you could take the JetBoil and boil water in two goes.
