Interesting to hear about the MS/iPeng lack of ability to add Qobuz favorites directly from those UIs. I was thinking of switching from MoOde to PiCorpPlayer and giving those a try. However, I may just stick with mConnect and MoOde since I’m able to manage favorites from within the app.
The mConnect interface is a bit clunky, but useable once you learn it. My biggest issue with mConnect is the battery suck it puts on my iPad. If I leave the app connected to my RPi for UpNP it keeps an active connection and drains my battery relatively quickly. The app doesn’t seem to have a Stand By or Sleep mode. As long as I remember to switch source from MoOde UpNP to iPad when I’m finished listening things are ok.
I thought about trying MoOde as well but I am not really fond of the look of the mconnect app.. Regarding audio quality and feeling, I don't know what's best between MoOde/UPNP and pCP/LMS..
Concerning your battery issue, I suppose it is the same with Material Skin/iPeng?
