You are right about not all bettas being alike and some getting along fine with a certain fish, while most wont.....but for me I'd rather not have to worry if I have a nice betta or an aggressive one.....because they can get along fine when you first introduce them..and then a week later,after they get adjusted and feel safe and secure in their new home......just when you let your guard down....WHAM....someone gets it....lol...
I don't like that kind of stress.....
