• Anime - AniList with the MAL-sync browser extension
• TV/movies - Simkl

Pros:

• MAL-sync provides automatic tracking for anime/manga but it’s limited to certain websites
• AniList is just a better MAL
• Simkl has some nice list features

Cons:

• I have to update Simkl manually
• I don’t have a way to automatically update AniList if I download anime, but its still more convenient to use the extension to update manually anyways
• Simkl bugs you to buy premium
• Neither of the sites are open-source
