All of those brands make filters for BMW.
The difference is that BMW puts its stamp on a certain number of the best parts, so there's a marginally higher chance of good quality when you get something with the BMW label vs. the "same" part from the original manufacturer.
This is true of any manufacturer, really. Or at least any manufacturer that has its stuff together.
