Every snake will have its own personality. Caesar my SD retic was a very mellow baby. He has never tried to bite or hiss at me. He did open his mouth at the hook though as he hates them. I use a twisted paper towel to boop his head if he's being 'bad'.
Be aware though that if you get a burm or mainland retic, you are going to need a 10x3 or 10x4 cage and they eat a lot. Caesar eats a 2XL guinea pig every 10 days.
As for being moody, Caesar sometimes pushes my hand away when I'm bugging him and he wants to be left alone or sometimes if I'm petting his head or neck and he doesn't want it, he will push my hand. But most of the time, he is happy to come sit at an open cage door while I clean poop or pee and just sits there next to me.
He's not a huge fan of being carried around like my boas but he does like interaction for sure.
I have never owned a burm but I hear they are pretty laid back. But they also get much more girth to them especially females.
My advice is if you have never owned anything on the larger side like a boa, but really want something, go for a high percentage super dwarf retic. Here's Caesar and hes a 37.5% super dwarf, 31.5% dwarf, 31% mainland and like I said, he is pretty laid back. I am pretty sure he wouldn't bite me unless he smelled food. Then I know for a fact he would bite me lol. He gets stupid during feeding time and bites first and asks questions after.
Oh and I forgot to add, also remember, it will take a lot longer to clean them too lol. It takes me about an hour to clean each of my 6x3 cages. Now I might be being too meticulous but that's what it takes me. That's why I usually do all the cage cleanings over a weekend.
