I’ve met snakes and they were not too scary and patient if you don’t touch them.

While primates I see every day are much more dangerous, and this one also is too strong and dumb to mess with.

Still, with the gorilla I’ll at least be able to realize that I’m going to be dead before I’m dead, but still breathing.

With such a snake that’s very much not certain.

So not sure, I’d throw a coin.

EDIT: Survival-wise I’d choose snakes, if that’s not clear.
