I mainly use Anilist with Taiga to auto track my watching. I also use the Automail userscript for some bonus stuff on anilist, and douki to sync with MAL every once in a while.

AniDB seems to have the best database, as its name implies, so I go there often to look up minor credits like episode directors or song composers. It also has tools to track your locally downloaded library for those who like to build their own collection.

I'll throw my list in here cause its my first comment on lemmy https://anilist.co/user/Pencilsharp333/

I use Anilist because it has the best API. The best API means that it has first-class support across every single app in my anime "stack":

• AL-Chan (Android client)
• MAL-Sync (Webextension)
• Miru (Desktop anime viewer)
• Saikou (Android anime viewer)
• Saikou TV (AndroidTV anime viewer)
• Tachiyomi (Android manga viewer)

I still use anilist with MAL sync.

AniDB is superior but it has three downsides:

1. Terrible, terrible defaults, extremely confusing if you don't customize it.
2. UI is weaker compared to Anilist.
3. No manga tracking. That's a big one if you like manga.

But it has the B.E.S.T. database by far and it's highly customizable. I use AniDB, if you opt for it, you can send me PMs here and I'll help setting it up.
