I never use white gas or alcohol stoves, only propane/butane, even in winter. Has worked well for me over 25+ years of mountaineering, so I won't change that. The only thing that has changed is the weight and efficiency of the stoves. My current stove/pot selection ranges from a Vargo Titanium mini burner that's about 3 ounces and mates well with a super thin 1.2 liter titanium pot - good for 3-season solo trips, but as of late it has lost out to my new Jetboil Sol - super light, although I have my doubts about reliability with all the plastic on there. Still, more efficient than the Vargo and super light as long as you can live with an 0.8 liter pot for everything.
For group hikes I have a Gigapower stove that sits nice and low to the ground with remote canister, and it can handle a pretty large pot without getting unstable. As of last winter I also have a Jetboil Helios for cold weather and group use - very efficient, but rather bulky with the 2 liter pot. It can also take a 3 liter pot if you're in large groups. Worked very well at -10F on Whitney melting snow this winter. The Helios comes with a nice windscreen that keeps things going pretty well, while for the other setup I need to bring a custom foldable aluminum screen or just use the terrain.
These bigger stove/pot combos do not make any sense in solo outings. The Jetboil Sol or Flash are pretty much the thing to get for efficient and reliable water heating. Everything else that weighs a little less is a much bigger PITA to deal with.
For summer trips I have considered trying one of the very efficient wood burning stoves. Not sure if I want to deal with that (especially after a rainy day), but there are a few ounces of weight savings in the cards if you can wait for the coffee a little longer and carry branches up a mountain pass if you need to cook above 10,000 feet. There are some rather efficient designs out there that work with just a few twigs.
