ummmm... well burning آپ would feel your flesh being heated away and being singed and I don't think that is a comfortable feeIing but drowning آپ would feel the water getting to آپ and the lack of air would be a very torturous feeling so I don't know. but are very slow ...
Neither is the best way to die. Slow painful deaths? are آپ crazy? I think, this is me سے طرف کی the way, that the best way to die would be in your sleep. No pain.
Neither of these are the best way to go...Other than dieing in your sleep I can't really think of another way that would hurt less یا even hurt at all.
