From Plex to Jellyfin Media Server

I have used Plex for about 12-13 years but am very very far from a power user. I find it mildly annoying I need to login but other than that I've not noticed anything that annoys me. I admit this is most likely due to how little I use it and how non-advanced that usage is. Given this, is there any value add to Jellyfin for someone like myself?

My read on this article is that it gets back to an earlier, more raw state of Plex. For my use case my interpretation is that would mean extra work for potentially lower quality, and unlikely any value add given that nothing annoys me about current Plex. Does that sound right?

If you don't want to pay for Plex then you don't have hardware transcoding. This is of course free in Jellyfin.

Who has hardware for transcoding any more, and what hardware is modern for that?

Last dedicated hardware encoder I used was bad old days of MPEG2 for DVDs, but that went the way of the dodo when MPEG2 went native to the CPU. Never used hardware for h.264/5. I guess there was a board for J2k doing realtime lossless, but that was 2010ish.

So I'm legit curious what hardware transcoding looks like today, and that Plex charges for the pleasure

I bought a GPU to get smooth 4k sources streaming to my devices.

Why are you having to do realtime transcoding for streaming to devices? Why not just have a streaming version? Transcode one time at whatever speed, then it's ready for you whenever you want it anytime after that? Not that you can't do whatever you want to do with your own gear or anything. I've just never understood the desire for realtime encoding for everything
