Those are what most real pool players call "bar rules" and most bar players refer to as "straight eight" and are played in 98% of the bars across the US (with slight variations sometimes between bars or areas of the country, like whether after the break you are what you make or it's still open). The only bars not using bar rules are the ones that have a high number of league players which hang out there in which case they often use the rules of whatever local league they are affiliated with (BCA or APA etc).
You will never convince a bar rules advocate that BCA rules are better. You can show him the "official" rules online, and even though he can't show you any set of his official rules, it won't matter. You can tell him that all the professional tournaments use BCA rules, or a close variation thereof. It won't matter. You can even show him youtube videos of the players playing on ESPN with BCA rules and ask him to show you any video of a professional tournament using bar rules. It won't matter and won't change his mind. You can tell him every actual pool hall in the world uses BCA rules or a slight variation from BCA. It won't matter. In his mind BCA rules are "sissy rules" for people that can't play or who have no heart. If you were a real man you would call every rail bump and ball contact. If you were a real man you don't need ball in hand anywhere on the table. If you were a real man you would take the set of balls you make on the break, etc.
When you haven't played a lot with BCA rules and aren't a great player (which is almost all bar players) you will never be convinced that not having to call every rail bump and ball bump and having ball in hand anywhere on the table is a better way to play. You simply don't yet have the knowledge and skill or the exposure to it to be able to see and it will seem very counter intuitive to him.
My suggestion is to tell him that all the pool halls with the top players, and all the professional players, and all the televised tournaments use BCA rules or a variation thereof and that only bars use bar rules because they don't know any better (he isn't going to buy it). Then tell him since you are used to the "official" rules, and he is used to bar rules, that you will play half the games one way, and half the games the other way. Race to 3 with bar rules, then race to 3 with BCA rules. It's a good compromise because you are both going to hate half of the night and neither of you has to hate the whole night.
