I'm very very late to this thread. But my blood python Travis is my favorite of my snakes. Yes, when he goes to the bathroom it is an "event" and a pain to clean up, but the rest of keeping him is a joy.
No, he doesn't move that much, but he has a "cute" personality. I have to drop feed Travis because he wont eat if I'm in the room, a quirk that took a while to discover.
Travis also loves to soak in his water dish and poke his head out of his hide to see what's going on when I'm in the room.
Handling wise, you can sit and hang out with them without constantly making sure they don't crawl into the sofa (happened with my ball python one time and I had to cut open the back of the sofa to get him out). They're kind of, calmly inquisitive about the world around them. He's the snake I bring out when someone wants to hold/see one of my snakes.
