Streamer Apps...how important?

Thanks in advance for any help with this. 

Some manufacturers put a lot of effort into iOS & PC apps for their streamers (e.g. NAD, Marantz).  These apps incorporate a long menu of streaming services.    Besides "one stop shopping" are there any benefits vs. playing through the Tidal, Sirius, etc. app and then connecting via Bluetooth in my iPad's Settings app?
