What is better? My colonoscopy came with a dose of propofol that made me understand why Michael Jackson went out the way he did. Best sleep I've ever had.

I hope that is forever the only difference. However if you actually have a deadly form of cancer (not all are worth treating, but that is a different discussion) better is whichever one gets you the correct treatment sooner. By contrast if you don't have cancer is whichever doesn't have side effects.
