From 'Stock Android' (Nexus, GPe) to 'Skinned Android' - What Do You Miss?

  • Galaxy Nexus
  • Nexus 4
  • HTC One M7
  • Note 3
  • Nexus 5
  • HTC One M8
I've carried a lot of devices in the past couple of years, and have experienced most of the major "skins" on Android. Switching back and forth between 'stock' and 'skinned' Android has shown one thing to me - that Android is Android. My needs in a mobile OS are wholly satisfied with Android as a platform - rich notifications, customizability, different hardware to fit different needs, strong Google app integration, and easy access to relevant data (e.g. Google Now, widgets, and good apps).
So with that said, the only thing that I've noticed - bugs. I've found that the Nexus devices, especially the Nexus 5, are pretty much bug-free in daily use. Sure, there might be some hiccups with new apps, but in general, I don't see the persistent errors or bugs I would see on the Note 3, whether they be hardware (e.g., proximity sensor) or software (i.e. TouchWiz). The M8 has it's own share of bugs, mostly related to the radio firmware.
But I don't have a strong preference for being a 'Nexus Warrior' or an HTC evangelist - they're all good and useful IMO. Thoughts?
