Unless your home internet has multi-gigabit upload, you'll never be able to compete with seedbox users when new uploads drop and everyone is downloading them at the same time. Your seedbox can upload at 10x-100x the rate my home internet can which is why seedbox users capture all the seeding credit on new uploads. Once a file has been out a day or two, the only people downloading are new users or people who aren't using automation tools like sonarr/radarr which are few and far between.

The tradeoff here is that your seedbox storage capacity several orders of magnitude lower than my 50TB home server, so I can keep these files seeding forever much like the parable about the tortoise and the hare (though without the deeper meaning).
