I think WiFi functionality would be enough to address low angle shooting. I'd take Wifi over flip screen.
Disclaimer: I acknowledge that each will have his/her own preference, and that my opinion is just that.
Having used both WiFi with EOS remote and articulating touch screen extensively, I would take the articulating touch screen
any day of the week over WiFi control via tablet/phone. WiFi with EOS remote has its uses and is appreciated, but it is simply too cumbersome, awkward and tedious to be practical (let alone enjoyable) in most of my shooting situations. It just doesn't even come close.
It you're shooting landscape or architecture or things that don't move, or animals you can't get close to, and you have enough time, and you have enough hands (or brackets?), WiFi and EOS remote will work. For most anything else, I just can't be bothered with:
1. Turning on WiFi ('cause leaving it on all the time drains battery)
2. Launching EOS remote, connecting device.
3. Holding/looking-at remote device to compose while positioning camera/lens.
4. Dealing with the lag between what's happening and what you see on the remote device.
5. Having no free hand (or having to add the bulk of a bracket to have a free hand).
6. Remembering to turn WiFi off when done with the shot that needs it.
7. Rinsing/repeating when low/high/odd angle is needed again.
8. And a whole gaggle of other potential hassles...
Versus:
1. Flip-out the screen to desired orientation.
2. Press Live View button.
3. Touch to focus. Immediately.
4. Take the shot(s).
5. Close the screen.
The articulating touch screen is simply a joy to use.
Just my opinion...
