I prefer the A B C method. Just because I always see it beeing used and I think it's good to have one preferred way of doing the mechanic in contrast to ppl argueing/disagreeing over what would save 1 Minute over a 30 Minute+ run and eventually eff it up.

Couldn't care less if one or the other method is slightly safer or faster, key is having a established method that a group of 24 random players can work with.
