Can't agree more about the difference between Spotify and Deezer. Spotify has a better user experience. Subscribed to Deezer and tidal but found myself going back to Spotify. Just my 2 cents.
I bought a Samsung Q70T within that price range at Makro on promo. one of biggest advantages (for me) is the eARC vs. ARC on the Q60T. If Atmos is important to you.
