Why many Companies leaving NAV/BC and going to Odoo?


I am just wondering if someone did a deep comparison between NAV/BC and Odoo Enterprise,

I’ve seen a lot of companies just dropped AX or NAV/Business Central and implemented Odoo.

I got many invitations to work in Odoo implementation, but not yet decided.

I hope someone can share more about Odoo and how to negotiate with the Company to let them adopt NAV/BC and not to go for Odoo.
