If you just host for yourself, you don’t gain that much by using Seerr, besides having a nicer UI and you have more search filters compared to Sonarr and Radarr.
However, if you have multiple users, you benefit a lot of it. Users, which have individual user accounts, can request media. Depending on the configuration, those requests have to be accepted manually, which gives you a way to still be in control of what ends up on your server. The user then gets notified about what has happened and if the media was downloaded.

Media requester for Plex and Jellyfin. But also tells you where things are streaming. A mix between IMDB and JustWatch.
Overseer was for Plex
Jellyseer was for Jellyfin
Now we have Seer one platform to do both.
