Not sure about my favorite. My most often used is the MSR WindBurner.
In cold weather I invert the canister on a MSR Wind Pro.
Have also used: MSR Pocket Rocket, Soto ODR1, MSR Whisperlite, several iterations of the JetBoil. I use a Light My Fire striker to start them, love that little thing. My best advice on a stove is make sure you keep track of your boot laces when using the stove to un-freeze them in the morning
