When you can do both get and set on a property, then I personally like to have direct access to the variable. For me this is the clearest way:

$obj->{property} = 'something';    # for setting
$somevar = $obj->{property};       # to get the value

I just don't see the any advantage in using a specialized functions for it. Getting and setting values of variables is something so basic for programming that I find it the most intuitive way for the task.
