Plex is a taboo topic anymore because of their recent business-focused changes. I personally use Plex as I've been a user since the early 2000s with no intentions to learn the nuances of Jellyfin, and get my remote streamers moved over to it.
Plex mixed with Sonarr, Radarr and Overseer fits my needs perfectly.
I haven't played in a while and I think my max is two challenges. Just wanted to say good work!
