Bros deck is good for sure. I have friends that use it and love it. I just wanted to highlight that in Firecracker, the notecard gives you the answer. If you feel like you want to review the topic, you can click "more info" and it gives you a paragraph that is enough for you to understand why. Then, you can click to get even more info, which brings you to a page full of info on that and related topics to show you how it all works together.
I've got classmates who use bros and are top of the class. It is defnitely good, but yes there are differences in the amount of info you get. Anki will help you memorize facts you learn in class. Firecracker can help you learn it if you didn't already.
I feel like a salesman.
