hi-fi kit blueOS vs stream magic with ios?

Hi everyone, hope you're doing well and staying safe :-) I have an existing hi-fi system that I would like to add some kind of Internet streaming device to. I will be streaming from iOS and also my Mac.
The two options that I've come across our Cambridge audio products with the stream Magic app or blue sound with the blue OS app. Which one is more accessible across iOS and Mac blue OS or stream Magic? Does anybody have any experience with these please? Thanks very much for your help everyone looking forward to your responses :-)
