Well it depends on which tracker I would really consider my "first". My first was demonoid, but I wouldn't really consider it a "private" tracker considering how often it's open, the external torrents, and how people who don't have an account can DL from it.
My first private tracker that actually cared about my ratio/seedtime would be TL, and I think I would've survived just fine. Almost all the content I want is there, with the rare exception of some VC games I get on BCG, and its easy to seed. I think I would've done just fine.
