It depends on your cooking preferences.
The new remote-canister stove burner is a more versatile stove design because it provides the ability to cook with the new larger WindBurner pots. If you plan to cook for groups or make more elaborate meals in the backcountry, the new remote-canister stove is an excellent choice. It comes in the new WindBurner Duo System, the Group System and the Combo System.
If you simply want to boil water fast, and your party size is typically only 1-3 people, the 1.0 L Personal System or the first-generation 1.8 L System (which feature the stove that mounts directly on the canister) remain great options.
