UJM: I have Bar Ilan and am very happy with it. I appreciate having the Encyclopedia Talmudit, the scope and accuracy of their texts, having the texts in text format, and the fantastic search engine.
I would love to also have Otzar haChochma, either the Bnei Torah or the regular edition. If you’d like to purchase either one for me, I’d be thrilled.
However, you were the one in the marketplace and were asking what the differences were and I told you. The Bnei Torah edition removes 1,500 seforim that appear in the regular edition and the criterion for exclusion is hashkafic.
As I said, I’d be happy with either one.
