What I like about the Anki approach is that it’s very conducive to scheduling and timeboxing. It removes a lot of variability from the process of memorizing things, and for me variability/unpredictability is a point of significant friction and a strong determiner of if I can consistently work on learning something or not.

In some cases one can also use decks made by others, which can help avoid wasting time on dry, unnecessarily fluffed up instructional materials with low signal-to-noise ratios like is common in university courses.
