The reason why live feeding gets such a bad rap is because so many morons leave rats in with snakes overnight. That is asking for serious trouble, and that's how snakes get so severely injured. With suprevised feedings of appropriately sized rodents, it's not a problem. I've had a live rodent take a bite out of my snakes several times. If the snake doesn't kill it at that point I remove it. One of my BPs even bled a bit once, but with clean substrate and a little neosporin, she was completely healed within the week.

Personally, I feed f/t because it's cheap, can be purchased in bulk, and does not require feeding and watering. But that's just me. I'm not opposed to supervised live feedings.
