SA and EoSD involve pretty different gameplay styles for first 1ccs, in my experience.
SA gives you more bombs and lives, and has the graze-autocollect that can help you recover power if used well, so memorization helps more with SA. Meanwhile, EoSD is more about random dodging-- memorization helps too, particularly in stage 4, but planning your bombs isn't as effective in my experience (due to fewer resources, the rank system where patterns get easier if you've recently died, and bosses' more random movement meaning patterns take a more variable amount of time).
