well it depends on the snake itself and not the species in my oppinion. For example:
I keep 1.1 Naja melanoleuca.. I bought the male allmost 2 years ago and am ( according to other herpers) extreemly lucky with his behavior.. He has until now never hooded at me. Never has he even tried to attack me or show any kind of aggresive behavior. He is allways watching me when I am in the room and when I want to do his cage he pulls back his head inside the hidebox and I could leave it open ( but I don´t do that cause I am not ignorant and thinking I know my animal and get bitten anyway)when working in the cage..
Now last year I bought this baby female and man is she a [bleep]!!!! She is allways looking for a way to kill me.. It is even hard to feed her cause of her extreemly aggresive behavior and she emediatlly hoods when she spots me and will come towards me standing far up and very fast so that she is allmost coming in striking range .. She is allway like this!!!24/7 !!

The other species that I got are prety much calm with an outburst every now and then.. The Naja naja and Naja siamensis that I got are the 2 species that together with te melanoleuca are often pissed ..
