I only have experience with one, but mine is a sweetheart to handle... during the day. At night, I can't even get close to her cage without her striking.
During the day she is a very easy going, curious snake that loves to stretch out when she finally wakes up. She's never shown even an inkling of aggressive tendencies during that time.
Mine is the same way - easy to handle during the day - active tho not sluggish like a ball - but come sun down anything that enters the cage is grabbed, wrapped and eaten - be it a rat or a hand.
