I've head about private tackers forever, is it that much better than public? I have never really had an issue with public trackers ,but also never had an invite to a private one
IMO, yes. Just for the consistency of quality and absence of fuckery. Damn near any TV show/movie/documentary is on there in at least 1080p, usually in 4K for newer stuff. For music I use SoulSeek and for eBooks I use LibGen.
