Bite difference between Amazon Basin and Northern ETB

[Bodega aquatics]

Hello! I am interested in getting an emerald tree boa or a green tree python and I had a quick question about the ETB. I know that they are definitely known for their nasty bite and I was wondering if there is a big difference between the northern vs amazon basin localities in the strength and damage of a bite. If you do get bit, would it require a doc visit or stitches? If so then I'll go with the GTP. Just curious because the Northern ETB and the GTB seem so similar and I'm really having a hard time deciding. Thanks!
