Free sentence mining (Yomitan + asbplayer) vs Migaku

Both let you look up words while you read and watch, and turn them into flashcards. The difference is cost against setup.

Which should you choose?

Choose it if you don't mind an evening of setup and want everything free. Pair it with asbplayer for video and ttu for books.

Choose it if you'd rather pay a subscription than set things up yourself, and want lookups and cards in one product.
