> rambam or a mishnah berurah? I should hope it’s the latter.
My limited understanding is that MB is trying to develop a comprehensive halakha harmonizing multiple sources, including some old less known ones. As such, it is not really representative of possible specific traditions. This makes a lot of sense in the modern world when people are exposed to multiple approaches, but if you do have a specific tradition, you do not have to look MB at all.
