<< Being able to operate it via a mobile device is the key benefit I'm seeking. >>

Operation via mobile device becomes a useful feature for live shows when there's many more inputs/outputs and digital audio features than what you've listed. Otherwise, a good analog mixer is a much better option.

The top failure point of live shows is cables and mics, not mixers. Wireless failures is the number one issue with digital mixers followed by being at a venue where overheating is a possibility or bright lights/sunshine masks the mixer's lights and displays. All digital mixers are, for all practical purposes at a live show, a computer. Venue voltage issues, long power runs, heat and operator error can easily cause a digital mixer to shutdown or reboot. Lose the digital mixer without backup and you lose the show.

I worked sound for a high-end tribute band for several years where we used digital but most time set up two Behringer X-32 mixers so if we did have some sort of mixer failure, we could transfer between mixers very quickly. We never had to, but were prepared had a failure occurred.

The digital mixer you're considering is in my opinion a niche device and as others have noted, there are many better options. If operation using a mobile device is a particular need of your group, one of the Behringer XR units would be a better solution.

Nearly anyone can stand in and operate an analog mixer that's been initially set up, not so for a digital mixer. It has a computer O/S and dives deep into menus for nearly every possible configuration change necessary when mixing a show. EQ, Compressors, gates, routing, sub-groups, aux sends and returns are all menu items. Someone needs to know what they're doing in order to step in on short notice for the regular sound person.

Anything can fail for any number of reasons during a live show. I've personally owned and used a lot of Behringer equipment and never had a single Behringer device fail. That includes mixers, monitors, tops, digital stage boxes, headphone amps, digital in-ear monitors and more.
Our shows have experienced failures of Mackie tops and subs as well as QSC Subs and Crown power amps.
