The thing with cooking in the tent, other than ventilation (which most tents can do, to varying degrees of letting the rain in), is stability. You *really* don't want something that's easily knocked over - not just because of what might catch fire, but the more boring practical issues of what you do when you've got a boiling pasta slick edging its way towards your genitals/sleeping bag and your escape route is blocked by a hot burny thing.
Trangia (ideally with a gas burner, to avoid fuel spillages) is probably the gold standard for cooking within tent, on that basis. Precarious little gas stoves that perch on top of the cylinder are right out. That MSR looks acceptably stable, so it comes down to whether you're skilled enough to light it without creating a fireball...
