When my dad was attending a JW conference while studying with Witnesses, he picked up an evangelical tract on the ground. A Witness grabbed it from him, crumpled it and tossed it on the ground saying it was apostate literature. My dad came back afterwards and picked up the tract and out of curiosity, read it. It wasn't much later that he became an evangelical Christian. His moto after that was, "After religion, try Jesus"
One difference was, that he retained the truth about no immortal soul and eternal torment.
