[Q] Best voice-controlled AI for RasPi3?

So I'm planning on putting together a somewhat smarthome controller - it would be responsible for stuff like waking me up, doing some basic stuff (telling the weather, etc.).

What is the best solution currently out on the "market"? I know of Gladys, Mycroft and of course, the half million ways of getting Alexa to work.

My current setup is quite simple, a Raspberry Pi 3, and a PEAQ Bluetooth speaker that also support HFP (so in theory it can act as a continuous listening device). I'm currently setting up Raspbian (would prefer Ubuntu Core but I have no screen available for initial setup), but all recommendations are welcome.
