Another stove question

With so many topics about stoves I'm even more confused
I'm after a stove that will work in all conditions, I like the idea of gas as it's easy to use, most will simmer and I have read that if you invert the canister you can use then in sub zero temperatures. Have I understood this correctly?
Can someone just point me to the models from MSR, Primus, Otimus etc that are gas stoves that will invert the canister for cold conditions. I guess cold is Vic and Tas and NZ conditions in Winter.
I'm really trying to find a stove that will work in all seasons all conditions.
Thanks
