I'm not looking for specific brand-name fuel; any brand is fine. I don't think there is anything special about the Jetboil brand fuel, other than the high price and the fact that the fuel canister fits in the cup. I want a larger canister anyway.

You will need to boil a hell of a lot of snow for a sufficient amount of water and I am not totally convinced of it's dependability at high altitudes. I have a Jet Boil myself and love it but in my opinion it is well worth the extra weight of a MSR XGK.
I'll need boiling water for the "dinner" meals, but I'm probably going to use a lot of the granola meals, which require only cold water. This is partly for the purpose of saving fuel and partly because I actually like the cold granola more than a lot of the hot "breakfast" meals. I found some spinach-cheese omelet things that required a frying pan, like I'm going to bring a goddamn frying pan to 19k.
If the cold temperatures become a problem with the fuel canister's performance, there are ways to warm the thing before use, and it only needs to stay warm for several minutes at a time. Obviously, if elevation is a problem, there isn't much I can do. But according to some
testimonials on Jetboil's website, the thing works at high elevation. Their website seems to be going slower than stove fuel in January, so I copied some of the quotes:
I was amazed at how well Jetboil performed while guiding on Aconcagua. At 19,000 feet using the Jetboil made things so much easier.
So, apparently it works at Berlin, which is as high as I'll need it. Of course the manufacturer wants to sell their product, so this may all be bullshit, but I think it seems legitimate.
We were . . . a little anxious to see how they would do at 20,000’ and above. I always knew that we would be able to count on the stoves working; what I was really concerned about was the fuel. Well, everything worked as if we were using it at sea level.
Well, that as-if-it-were-at-sea-level crap may be an exaggeration, I suppose.
We used the Jetboil in Camp 2 of Baruntse (21,500’) . . .
. . . for a deadman anchor. (Haha.) No, really it goes on to say they cooked with it. I hope it's not a lie.
