What is the difference between these two methods for defining property value defaults?

Code:
    Public intSomeInt As Integer
    Public strSomeString As String
    Public objSomeObject As Object
    Public booTrueFalse As Boolean

    Sub New()
        intSomeInt = 100
        strSomeString = "DefaultString"
        objSomeObject = strSomeString
        booTrueFalse = True
    End Sub
Code:
    Public intSomeInt As Integer = 100
    Public strSomeString As String = "DefaultString"
    Public objSomeObject As Object = strSomeString
    Public booTrueFalse As Boolean = True

    Sub New()
        'Constructor code here
    End Sub
Is there a reason to use one method over the other for defining the default property values in a class?
