If you like to play your music directly from FLAC files and buy high definition tracks at a great price, Qobuz will be for you. If you want to try streaming music in MQA format and discover new hip-hop songs every day, Tidal would be a good choice.
In my opinion, both have their strengths and weaknesses, but the winner really depends on the user's preferences and the songs they play. I'm a big fan of Tidal MQA and will often use Tidal Music Downloader to download my favorite Tidal music locally without the costly subscription fee.
