Have you looked into the details as to which services and file handling each can do and how you control it? Do you have an NAS server or are you looking simply to access internet based streaming services?
I have no NAS but do have a Tidal Hi-Fi account and 390GB of music stored on my Bluesound Vault (backed up on a USB hard drive) and the app for my tablet runs everything beautifully. Very happy with Bluesound Tech Support too, as I had trouble getting my files onto the device. That was on my end, not their device but they helped me get it working.
