One of these is among the most effective study methods. The other is among the least.
Verdict
Flashcards force you to retrieve an answer from memory, and retrieval practice is one of the most consistently supported study techniques there is. Highlighting feels productive and mostly produces a colourful book, because recognising text is not the same as recalling it. Use flashcards as your main method; use highlighting sparingly, to mark what you will turn into cards.

You want study time to translate into exam performance. The value is not the cards, it is being forced to produce the answer before checking, and then seeing what you got wrong. Sort cards into piles by how well you knew them and revisit the difficult pile more often.
Flashcards win because they are practice testing; see how to study for college exams for the full plan, and note-taking methods that turn lectures into questions.

Because rereading highlighted text feels familiar, and familiarity is easily mistaken for knowledge. The uncomfortable feeling of trying to recall something and failing is what actually strengthens memory, which is why effective study often feels worse.
Reviewing material at increasing intervals rather than all at once, which is generally found to produce much more durable retention than massed practice. Sorting physical cards by difficulty is a simple manual version of it.
Both work, and the technique matters more than the medium. Paper is cheap and has no notifications; apps schedule the spacing for you. Choose whichever you will actually keep using.
