I've never tried grid because I'm not a fan of visible picks, but pancake definitely seems very good. I like the part where you trash cards from the boosters to somewhat simulate a more-than-2-people draft, and makes hate drafting way easier
the person i'm doing this with is a much more casual magic player than i've been in the past, and what attracts me to grid is they can see my picks and learn from my thought process as we play. the endgame for me is definitely sticking to pancake, theoretically.
