Best employee pricing for Premium suv

My company offers Employee pricing through most manufacturers…

  1. Is this the better way to go? Or am I better off negotiating on my own?
  2. I am thinking about one of the below models… Any that specifically have a better “employee” pricing plan than the others?
    Mazda CX5
    Volvo XC60
    VW Tiguan
    Alfa Romeo Stelvio

Thanks!

Tiguan and Stelvio have very attractive lease deals right now regardless of “employee pricing”.
