What is the performance difference between MSR XGK EX stove and MSR WhisperLite stove if both uses white gas? I would like to know at what kind of condition XGK has better advantage than WhisperLite if both XGK and WhisperLite use white gas as fuel. Can XGK handle high wind (under condition of using windscreen) at bitter low temperature better than WhisperLite? In principle does plate burn handle cold high wind better than ported burner (such as WhisperLite)? Is there any quiet plate burn stove available or is it the nature of plate burner?

For lower altitudes (less than 8,000'?) the Whisper Lite is an excellent choice as it is lighter and MUCH quieter than an XGK, but at higher altitudes you really need the XGK. I'm not sure exactly what the difference is, but at the 14,300' camp on Denali, a Whisperlite will barely boil water, if even simmer it, while an XGK cranks out gallons of hot water.

Why would the temperature and altitude affect the white gas in one stove better than another?

Good luck trying to light a Whisperlite at 7000m in -29C temperature!

The XGK EX cranks out 10k BTU's & I feel handles wind conditions better since it is a plate burner. Once it gets going it's almost impossible to blow out. It is multi-fuel which is a big plus. Outside the US, white gas isn't always available but kerosene is. The drawbacks are it is heavier are much louder. The XGK & EX have proven themselves countless times on worldwide, high altitude expeditions. The WhisperLite is almost as hot, lighter, & the International version burns kerosene as well as white gas. Both stoves work great in all temperature ranges & when using the included wind screen & heat reflector become rock solid performers in windy conditions. Both stoves work great & will continue to do so for many years to come with a minimal amount of maintenance. A quiet plate burner stove is an oxymoron & has yet to be invented however the Primus Omni-Fuel is a bit quieter. FYI, if you use your stove without the wind screen, place a small piece of aluminum foil over the attached plastic pump especially during pre-heating. This will protect it from any flames that might flare up during this stage.
