Nice. I jumped straight to FSRS so I can’t compare, but so far I have no regrets. One of my features is I progressively disappear the furigana in the included dictionary and example sentences, as the reading proficiency of the kanji increases (specifically at 99% retrievability) https://github.com/runarberg/shodoku/blob/main/src/helpers/f... This feature was very easy to implement as retrievability is inherent in the algorithm (maybe it is in SM2 as well; I don’t know; but it was trivial in FSRS).
This library also makes it easy to undo a review (one of my missing features) as long as you keep the review records (which this library also makes easy).
Very nice to have these modern setups under freer open source licenses. I have all my data synced to the client to work offline, so it's very nice having FSRS available on iOS & elsewhere (+ ability to run the rust one)
I thought I recognized your username from a political debate here a few months ago. I figured you would enjoy the donations page of my app:

Glad to see solidarity among the Japanese learning community.
I'd like to port my own flashcards app, Manabi from SM2 to FSRS so this is helpful
I made this companion reader app as well, btw, for learning Japanese: https://reader.manabi.io
