Plex is pretty damn good. If netflix is "better", it's marginally so.
There is learning with the above... docker to start and NZB/Torrenting... server management...
If you know those things already? or are close? great learning experience (my case).
is it worth ~$14/month for Netflix? Prime? Disney+? HBO Max? etc? maybe... but at a certain point the 'nickel and dime' gets to a point to where learning how to do the above becomes more worth it.
You don't need an expensive computer/server to do all this... just time and a desire to learn. once done? you control your own library and no need to worry about losing your content if you stop the monthly payments.
Streaming used to be pretty good, when Netflix was basically the only one (with most content), but it's so fragmented now, that you need so many subscriptions that it's not cheap, and pretty annoying flipping between apps to find the show/movie you want to watch, then to find it expired last week, and you have to find out who still streams it.
I mean, don't get me wrong... streaming is still pretty good. Fragmentation of content aside, there's more good content than there's ever been. So I'm not a 100% doom and gloomer...
but...
Getting that content has the "provider" problem. As you say, whack'a'mole to get the movie you want.
People always bitched that "Cable is horrible! Why do I have to pay for 400 channels to get the 3 I watch!". And here we are... able to pay for "Ala'Carte" and it's exactly what everyone wanted - and expected: Paying more for each bucket. Instead of $100 (or whatever a full cable plan is)... you're paying $75 for internet, $15 for netflix, $10 for prime (or whatever it amoritizes yearly), disney+, hbo max, Discovery+, etc, etc, etc.
Finding the EXACT movie you want is a hassle... and that hassle is what drives me to Plex. Radarr/Sonarr/NZB/etc all roll together to make a massively good platform that, learning aside, hands all the power back. I do have to pay for some stuff (NZB, Plex, internet, time learning, etc) but it's my time and worth it.
