I have used a Pocket Rocket with great satisfaction for more than ten years, alternating it with a Trangia or Super Cat alcohol stove depending upon circumstances. I have always managed to put hot food on my plate.

I do keep some esbits around for fie starter or emergency use. They are fine, although the soot is a bit of a downer.

With experience, you will get a better idea of your fuel consumption with canisters. You can weigh them or mark the fuel line in cold weather. Spotty availability when traveling is the greatest negative with canisters, hence a light, cheap alcohol stove as a backup.
