It was several years ago for me, before I "used Linux", and was just a copy-paste user of Kodi and pi-hole.
anyway - my experience was similar, Kodi just wasn't worth it. I'm sure "it was the user" but either way, I stopped. Meanwhile the pi-hole is still going strong. And now all of our PCs are linux, so it's not from my inability to learn.
for streaming services, you could build an AndroidTV box, right?
