I am using LingQ for Japanese.

The translations using Google Translate are far from perfect. DeepL does a much better job, so I actually find myself having to go from one app to another translating sentences.

The SRS/Flashcard system is also in my opinion subpar to apps like Anki, which would've been nice to see implemented. So when clicking on a word or phrase, it would be nice to have an option to send that word as a card to Anki directly. Why try to reinvent the wheel?

Takoboto is just a nice to have, and my choice of dictionary that I would've liked to see, it also allows me to send cards to Anki, so right now I'm switching between LingQ - DeepL - Takoboto (->Anki)
