Columbian boas are the same as boa constrictors/red tails right?

I have always been scared of bein bitten by snakes. Ya ya i know its "wimpy" but im sure im not the only one who doesnt like getting bitten.

Columbians, being bigger than corns and ball python seem like they woukd have a lot of force and pain behind their bites.

In terms of temperament, are they any better?
