which is better? Emerald Tree Boa Vs Green Tree Python

[Bodega aquatics]

Hello! I am interested in either getting an emerald tree boa or a green tree python. I really like both but I have noticed that the GTP are easier to find and sometimes cheaper. Thought at the same time I do like the look of the ETBs just a little bit more. For people who have experience with these beautiful beasts, which one do you prefer? Also, one thing that would really sway my decision one way or another would be temperament. I know each snake is individual but I was wondering which tends to have better temperament. Thanks!
