I’d disagree that Anki is worse than Duolingo. Duolingo has some good ideas, but it’s poorly executed in the ways that most matter. I used a program very similar to Anki to build a solid vocabulary in Danish (when I was living in Denmark and learning it as a second language), and while I didn’t use it for grammar, it worked extremely well (but slowly, it took me 8 or so months to really cohere) for being able to know what words to use to communicate what I wanted to communicate. I find building a vocabulary like this in Duolingo is very tedious compared to Anki (while Anki is demanding, it flows very well when you actually do it, unlike Duolingo).
I would recommend a little bit of use of Duolingo just to familiarize oneself with the grammar, but I wouldn’t recommend using it as the main tool for language learning
