Similar to the other comparisons, some players prefer a B foot, while others like having a C foot. B footjoints are more common in the US, but C foot joints are popular in South America and Europe. If you want to play a lot of contemporary music, having a B footjoint is useful. However, it's not necessary, and it can add extra weight, making it harder for you to play the flute if you have arthritis or other health issues.
