Some XQD readers will work with CF Express B, but they have to be designed to do that. The reverse does work, CF Express B readers can handle the XQDs. No, you do not have to get a reader produced by the same company that made your card. Just do your research as to which reader is well regarded. I happen to use one made by Sony.
Not all CFExpress readers will read XQD cards. Look for a reader that specifies both.
