Disclaimer: All snakes have individual temperaments.
My stimsoni is the most placid snake i've seen. I can do anything to it and it will NOT bite me (although feeding response is excluded, its a REAL strong feeder and if it smells food, it'll strike at anything but if it didn't do that i would be trying to find whats wrong with it). It even drinks out of my hand when offered. And some of them have some real stunning patterns. Great first snake too due to the size.
The only con i could really think of is the max size. I got myself a bredli after my stimsoni maxed out but thats because i want the best of both worlds. Now i have that with a large and small snake.
