I think it's important to first to plan what you'll be cooking since a stove can limit your abilities. I use an old MSR Whisperlite. The pros are it's relatively light, a bit more versatile than just boiling water and it's one of the most simple stoves which makes it extremely reliable. I also carry a repair kit for it, which isn't an option with most other stoves. All that said, I think there are better options available today if your only need is to boil water. Stoves like the MSR Reactor, Primus ETA and Jetboil are far more fuel efficient, set up faster, and boil water quicker. It's that time efficiency that adds value to those systems. Less time setting up and waiting is more time hunting or enjoying the scenery. Those stoves also have built in wind screens which are a necessity in my opinion. Just a slight breeze in cold weather can really hamper something like the Pocket Rocket. If I had a need to buy a stove to boil water today, I would look into one of those.
