You hit the nail on the head with "easy to use". The main difference between quality streamers is the Human Machine Interface (HMI). I find some of them suck and some of them I like. It is a personal thing so it would be great if you could demo some of them and figure out how to search for songs and play them and see if you like it.
I use Roon, not terribly simple to set up but very nice to use. I hear aurender conductor is good. I had a bluesound node but can't remember if the controls appealed to me or not. so look closely at how you manage your music and play songs. I like doing it with my laptop in my lap. Roon I can do on my laptop, my phone, or my tablet.
What I didn't like was using either Tidal or Qobuz as my music managment interface.
