It kind of depends: If I'm hiking in good, warm weather (like now) then I carry my Whitebox setup. It saves a little weight over my next setup and the WB burner can hold a lot fuel for extended boils.
When the weather is iffy I use a Trangia burner setup. The burner weight is well worth the fiddle-free, bomb-proof reliability in all temperatures. When it is cold and windy I don't like to be fiddling around with some ultra-light system that won't work because it got dented and dirty, or can't seem to get primed, or runs out of fuel before I'm done with my boiling, etc.
I freezer bag cook too.
