Gas ones - I have a generic cheap eBay one that I cannot tell the difference between that and a Vango, I have a Edelrid Ti that is ace, and I think same as a Alpkit Kiro, son has one that sits off the cannister on legs from eBay.
They are all much of a muchness apart from weight and stability, and a home-made windscreen from disposable roasting tray works well...
As a left field couple of ideas:
I now use for non-winter trips the wonderful Speedster Stove - light, simple, stable and just *works*, and soooo much cheaper than gas to buy the stove and fuel it. I am a convert...sure, it takes a minute longer to boil - but so what, I am out in the hills, and have the time. All mine fits inside an AlpKit ti mug - fuel, lighter, stand, rest, stove, washkit, some coffee...
You can see it to the left in this pic.

I also have a Esbit Ti stove - it weighs 6g! Simple to use, with homemade windscreen. A bit wobbly, and the tabs stink so I double bag, but soooo simple and good even in cold. I think the speedster is better - but 6g!
