>I have checked and it has the second highest artist payout after Tidal, quite close actually.

The topic of artist payouts is honestly pretty murky and hard to pin down. Contrary to what you often hear, it's not as simple as different streaming services offering different fixed per-stream rates. So what you see one artist being paid might be totally different to another, based on their specific situation. What does seem to be universal, though, is that buying whole tracks pays the artist a whole lot more, so if supporting them is a chief concern then buy albums you like through Bandcamp, HD Tracks, or Qobuz, etc.

>The only alternative I'm considering is Tidal at 4.99 as well but it's slightly lower audio quality because that's their Standard plan, not the Studio one.

As far as digital formats goes, it doesn't make much difference to be honest. The actual improvement from "Standard" > "CD Quality" > "Studio Quality", or whatever the marketing terms are, pales into insignificance when compared to how well the music itself was recorded, mixed, and mastered. Seeking better quality master recordings for the album/tracks you listen to is key when it comes to better sounding music.

Also, take any comments that claim one service sounds inherently different/brighter/bassier than another with a massive pinch of salt - they don't.

>I'd use it on Android and Windows so no Apple devices

I haven't had much experience using AM through the new Windows app, but I hear it's... temperamental.

The best way is to take some free trials and see which service ends up working out giving you the best user experience.
