IMO Mallos trumps them all, even the Hebrew and English ones. It was the first to address mental illness, especially Borderline Personality Disorder.
Last Purim there was a Willi family dressed up as “Shmoigers”, the all time favorite goofy characters of the kids section – everyone recognized them – it was hilarious!
I also enjoy the “Shtern”. It’s well written and informative, but it’s mainly secular in contents.
