From Dalai Lama’s Book Buddhism: One teacher, Many Traditions, there’s a table comparing the Vinayas.
The main difference between the vinaya of Theravāda, Dharmaguptaka, Mūlasarvāstivāda is on the training rules (sekhiya, śaikṣa), second is lapses expiable by confession (pācittiya, śuddha-pāyattika), the rest has the same number of rules for each section.
“The number and meaning of the precepts in the three vinayas are very similar, and the differences are minor. For example, seven precepts concerning how to wear the lower garment in the Mūlasarvāstivāda are subsumed into one precept in the Theravāda.”

Basically, it’s understandable then that the Chinese Mahayana who had evolved historically to eat dinner, plant food, use money etc do not wish their laity to read the Vinaya cause it’s clear that a lot of the monastics are not following it. There’s some Mahayana monastic who does purposely follow the Vinaya properly too.
