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
Mostly just streaming, maybe some direct downloads i like paywalled / premium OC. I couldn’t really afford either anyway so I can’t say I feel too bad about it. If VoD providers wouldn’t have turned out to be so garbage I might’ve gotten one of them, but not if that means I can’t watch everything anyway. Like what’s the point? I’m not gonna subscribe to everyone or hop around services. Exclusive content kinda killed them in my eyes.
