What are you after fuel wise? Gas, Meths/Bio fuel or Petrol? I have at least one of each and they all do something a little better than the others!
Petrol is great for melting snow and boiling water for instance( as you probably know) but pretty poor at cooking as it tends to not simmer etc.
Gas is ok for both but can be problematic to get in some countries, and you always have a cartridge until you can find somewhere to bin it, plus you can never be really sure how much gas is left until it runs out once on the road. Not great in the cold either.
Meths/Bio fuel is very easy to use and surprisingly efficient in the right stove, it is often the lightest option as the stoves can be very simple, so reliable too. Fuel can also be a bit of a problem when travelling, though you can almost always find it if you Know what the local name is. My preference is based on what trip I am doing. For lightweight touring it's meths for it's lightness, packability and reliability etc. In winter I use the MSR as I am just looking to melt snow and boil water for dehydrated meals. Gas is usually for a quick overnighter for the convenience.
So it depends what you are doing with it. If weight isn't an issue I still don't think you can go wrong with a good old Trangia. I still have one and if I was still pannier touring it would still be my first choice for long trips, you can cook proper meals on it which is great after a few weeks on the road as dehydrated meals can get pretty boring pretty quick!
Alpkit make a very good little cartridge stove that would fit in a pan or a mug. https://www.alpkit.com/explore/cookware
bugger they have sold out, but you get the idea.
For alcohol stoves a visit to http://www.backpackinglight.co.uk/cooking.html
would be useful for info.
As you can see there are lots of options that can be made into packable systems, some have more flexibility than others. In regard to the Jetboil, it is great for boiling water etc for drinks and dehydrated meals, but sit a little high and can be unstable unless you hang them. I just think there are stoves that do the same thing for a smaller package and lighter weight, more stability too.
Hope the links help.
