I personally use a Jetboil Sumo Ti and a MSR Reactor 1.7L as my main back-country stoves.  I also use a MSR Pocketrocket as a backup stove.   These three stoves have served me well for a variety of trips and uses.  Please keep in mind I eat dehydrated meals so my use of a stove is purely to boil water.   If you are a back-country chef another stove might serve you better.  At some point I want to add a MSR XGK stove for winter camping.  I base this on having attended a winter camping / survival seminar with Learn to Return Survival Training. The XGK (and the previous generation version) was their stove of choice for extended cold weather use.

In the future I will write a more comprehensive overview of why I chose the stoves I did and what my experiences with them have been.  However, in the meantime I found a great article I wanted to share.   It comes from MSR, but none the less it might answer a few questions for those debating stove options and makes some recommendations on specific stoves for specific uses.
