Spotify vs. Apple Music vs. Google Play vs. Tidal: Which is Best

I like the Tidal site a lot, but Spotify has always had a larger library. Therefore I have both. It will be difficult to pick a streaming service as we are entering a brave new world with digital hi-res music. Roon looks very cool, and I may change to Roon soon. Many choices.... but I do like MQA whichever service is offering it.
