Plex is better at looking up show names, has an easier UI to set up more complicated stuff like hardware acceleration, has better clients across a variety of platforms… the only reason I’m using Jellyfin over Plex at this point is because I anticipate Plex shitting the bed. If you’re on Plex, there’s no reason to swap from it, and honestly if you’re comparing the two as a newbie, Plex is still a much easier option.

I don’t even know where to begin on the question of “reining in my personal bias”, other than to note all reviews are based on a person’s personal bias, and what they know about the gaming format and industry as a whole. I know it’s a tired trope, but everyone has personal bias, and game/game demo reviews should not try to be objective looks at games (it’s near useless). Reviewers should instead make their experience and opinions known from the start, or throughout the review. That way if their opinions are diametrically opposed, readers who don’t share the same opinions can readily discount it.

Also, while you can empathize with and realize that someone might like a game if they’re into that genre, you can only go so far. I have not played Vampire Survivors, but if it’s anything like FatalZone, I will gleefully state it’s not really a game. Or if I want to be less glib, not really a game I’d recommend for others. Again, for you this might be a good cue to discard my reviews as worthless for you. You should make your own reviews in this subreddit in that case, as it could certainly use more posts.
