Took this post as motivation to try some out.
Here WeGo: actually pretty intuitive! Better than OSMand and Organic Maps in terms of Car Navigation (actual Voice and not TTS Voice from android) and 3D sounds that you have to get used to but coule make listening to instrucrions in stressfull sitations easier. Also optional: speeding warning ring sound and shield head up-sound effects (yield, stop, train crossing, etc.) Each with a special sound so you might get better prepared for the next yield or stop sign since your NAV app told ya already that one is coming up soon.
Deezer: Well some usability things annoy me. Also some problems with the android tv client...
Bit the flow mode (random shuffle in genres or moods (happy, party, chill...) that also has a toggle if you want the shuffle be based of songs you have in your playlists/liked already or if you want to go on a jurney to find new songs.
Pretty geat so far!
Qwant: well the search results hit good. Dark theme is a lil worse than DDG's dark theme but thats just preference. Some !bang searches are not available though. DDG has many more listed than Qwant. But we're getting there!
