I use Anki to squash my leeches and BunPro to be my main guide to study Japanese Grammar.
I don’t use any other people’s anki decks. I use my own decks. That means I enter manually one by one anything I need to my Anki Decks.
And to use BunPro, doesn’t mean that I just use it for Study and then Review the SRS. No, I learn any references that BunPro links from there. One of my favourite Japanese grammar books so far is A Dictionary of Basic Japanese Grammar.
I used to use KameSame almost consecutively, but not anymore. I hope anyone won’t ask me why because I won’t repost anything I typed on this forum about KS. I just use Anki for this case, since I think I become more and more fluent in Anki. At least, up to my necessities. I’m still not an advanced Anki user though.
I still use KaniWani from time to time, only to review my burnt items.
Oh, and also, I use this book, for my Kanji writing practice. 漢字練習ノート 小学1年生 (下村式 となえて書く 漢字ドリル 新版)
