Sorry for replying so late. Have been busy with exams and re-flashing back to CM13.
Android N was indeed very impressive for the first build. However, in daily tasks, the bugs tend to be quite annoying.
The new features are something I'm really looking forward to, especially full width notifications and the enhanced doze. The standby time really improved with Android N.
Looking forward to the full public release this summer for Nexus devices.
