Personally I use public trackers the most and only recently private trackers for stuff in my native language.
I did setup i2p a few days ago and currently have only downloaded around ~1GB. Most of my bandwith (143 GB in / 135.5 GB out) has come from just having it in the background 24/7.
The advantages of usenet don't really apply to me (longer retention, faster speeds, no vpn)
Streaming i find useful for checking if something is worth downloading
Its amazing once you start to realize how little you can watch even when you are subbed to all streaming services. In the years I used Netflix and co my consumption changed to 'I watch whats available'. Once I pirated again and joined a similar Plex server with a catalogue which contains pretty much every movie and tv show ever made, even international ones, it changed to 'What weird shit I really want to watch today'.
Even if would sub to every streaming service available to me (which would probably cost 100€ per month) I could only see 20% of the movies I have watched.
