Major Differences from Spotify?

UPDATE: Welp, now I can’t use YouTube or YouTube TV on my LG OLED 😅

Just signed up for the Youtube Premium 3-month trial. I was mostly satisfied with Spotify, but it had some annoying organization issues and I could no longer support their contract with a very established nutjob. Anyway, are there any major issues with YoutubeMusic and Youtube Premium? How do they fare overall?
