I have been using Amazon HD for a year, but recently signed up for Apple music because I have a free 6-month trial period when I bought my AirPod Pro 2. I quite like the Apple UI, but I will note that if you use WiiM Mini (which I do), you will need to stream over Airplay, which is not lossless. Moreover, I've noticed that streaming Airplay to WiiM will cause some tracks to stutter, which is very annoying. I also don't like that Apple music doesn't incorporate podcasts.
