FWIW:
Stove that never leaves my pack/bag/truck...MSR XGK, multi-fuel (white gas, Naptha, Gasoline (any type),Diesel Jet A/B...(pretty much anything you can find that burns), a little loud (but I've been using it for so long I don't notice) easy to prime no matter what the weather/temp (IsoButane has issues in extreme cold) and field serviceable, it's been on every big mountain there is, and will never let you down. I've used mine from deserts to over 20,000ft. Depending on what you will be cooking (i.e. just boiling water for drinks/dehydrated meals,melting snow...you can simmer with it, but it takes a while to learn) it's a legend (in the same class as the Svea 123). The new XGK-EX is just as good, a little more compact with a flexible fuel line and folding pot supports, but I prefer the original (can still find new one's on ebay).
I do carry an Isobutane stove on my motorcycle trips, my favorite is a few year old Vargo titanium (no longer made, but built like a tank) but own Snow Peak and MSR (MicroRocket). All the major players are pretty much good stoves. Something you may want to look at is the size of the flame spreader, as the smaller ones tend to overheat light cookware, especially titanium. The SP and MicroRocket are better than the PocketRocket at even heating, and the SP simmer's very well.
For complex cooking, hands down the MSR Dragonfly is the way to go (liquid fuel stove) but the Snow Peak white gas stove is equally amazing at simmering, just a lot harder to get parts for (MSR stuff is a staple at any mountaineering shop)
Some people dont like remote canister white gas stoves, or white gas in general, but depending on how much you'll cook, and the length of your trip, white gas may be the lightest option (depending on the number of extra canisters you have to carry) and the only option IMHO at high altitude or really cold WX. Propane is great in the cold, but tank pressure and weight makes it really a no-go for anything other than basecamp/car/vehicle use.
Sorry for the longish reply, I have a passion for stoves, and have collected far more than I will ever need/use...not sure if I added anything to the discussion, but good luck with your stove
