If you want support for all HW features today, you have to wait for CE to come back as they focused on implementing Amlogic-provided kernel with AMLCodec for multimedia support and most (if not all) features work.
LibreELEC focus is on mainline which will eventually come also for N2 (if there are developers working on it).
Take a look at the nightly builds under Download. I received my N2 three days ago and CE runs like hell on it. The same way the new emuELEC from shantigilbert, if you are interested in retro-gaming. (emuelecv2.5)
