I prefer ?-> because it makes it clear that there might not be a receiver for the message send ->, much more than ~> which suggests that some kind of pattern or smart match is involved. In the Groovy language, they call it the Safe Navigation Operator e.g.
def streetName = user?.address?.street

    I do not personally care for ?-> because it reminds me of the ternary operator.

    I voted for ~> due to terseness & the implication of flexibility

    Wait! This isn't a Parachute, this is a Backpack!
