I agree that Anki is likely less developer friendly but its popularity does make up for that I feel, with ostensibly state of the art SRS algorithms being published with Anki implementations (https://github.com/open-spaced-repetition/fsrs4anki) out of the box.
Though as someone that's solely used Anki for language learning, I do value the ability to remember more words in less time more than ease of development so it's not unlikely Memoet is a better choice for other usecases.
