I started with Tidal when it first came out, and then tried Qobuz when it became available in the US. I decided to keep both. I listen through BluOS where the Tidal integration is much better than that of Qobuz. I find that Tidal has more albums and artists that I listen to, and sometimes gets new albums sooner. Qobuz, on the other hand, has more hi-res content. Personally, I like the Tidal interface better, and I also use their suggested "mixes" to discover new music.
I have noticed no significant sound quality difference between the two.
I also have Apple Music which is included free with my cell phone contract. I like the way Apple saves and sorts your favorite albums but, sadly, they don't want to make available their hi-res streaming to any third-party companies. I only use it for headphone listening since I don't want to tether my iPhone or iPad to my stereo system.
