At that pricing, an XR18 is barely any more for a *lot* more I/O and functionality.
Everything on these is "nearly but not quite". Nice to have physical faders, and understandable that they're not motorised, but they'd drive you potty. Unsure about Bluetooth control, too. At least with a network interface, you have the option of your choice of external router and a hardwired connection if required.
Given that you need an external device to configure this, why not go the whole hog and have a surfaceless mixer. I actually think the hybrid is confusing. Yes, it's small, but it's easy to mount a tablet/phone on a mic stand with a stagebox mixer in a more sensible location.
That said, I think I'm not the target market...
