Does this system provide the same level of content recommendations as the Youtube homepage? If so then I'll set it up tonight!

Part of the appeal for these privacy front-ends is the zero tracking, so you don't get the hyper-aware recommendations of normal YouTube. I'd say if that's a major selling point to you, you probably wouldn't enjoy Invidious.

Though, I'd recommend people try self curating a list of subscriptions and discover new videos a more organic way (friends making recommendations, or seeing videos on HN or Reddit). I personally have found my YouTube experience to be less distracting when I started using Invidious.

There aren’t recommendations like youd see on the YouTube front page. There are “next video” recommendations like YouTube though

Also in this realm, for Roku there is https://github.com/iBicha/playlet which works great when hooked up to my self-hosted Invidious instance.

I use Yattee on tvOS but lots of invidious and piped servers seem to all be very slow to load. Any server you recommend?

They recommend self hosting
