Credit unions certainly have their appeal, and the biggest advantage has to be their member-focused ethos, which often translates into lower fees and better interest rates. They also provide a sense of community, as they're typically local and aimed at supporting local growth. However, they're not without their downsides. Their services can be limited, lacking the breadth of options you'd find at a larger financial institution. Also, convenience can be a concern since they might not have as many branches or ATMs available.
