Anki vs SuperMemo

I realise that this isn’t the question you asked, but I’ve had only a little taste of Anki and none of SuperMemo. On the other hand, I’ve used Kitsun a lot and find it pretty damn great as an Anki style tool specifically designed to be a toolkit for language learning. It’s got dictionary, subtitle, and reader tools integrated ^-^

Plus, it was designed by a wanikani finisher ^-^
