I echo many of the comments above too, with only learning a grammar point when having done so from other external resources (YouTube videos/textbooks/websites etc).
I’m definitely more relaxed with Bunpro as it doesn’t leave a harsh punishment feeling when making small typo errors with the “Oops” button and Off/Minimal Ghost available in the settings.
I also embrace making mistakes there because I know it will make it stick to my old brain better (which is the point of SRS at the end of the day). With WaniKani, I have to use the Self-Study Quiz userscript to work on my leeches and avoid the accumulation of Apprentice items.
