1. I can record games with internal audio.
2. I like the eq with my new jaybird x3s so I don't miss audio mods.
3. There's a built in theme engine so I don't need substratum or cm theme engine. Plus themes aren't high on my list of important features but they are cool.
4. I never cared much about xposed except for adding a restart option which samsung ads on there phones.
For me rooting would be a waste of effort because I wouldn't use it for anything.
