Neither is really better in certain situations.
On real race cars, we would have the steering tie rods going slightly downward from the steering box arm to the spindle arms. This was so the toe would be the same amount under braking (tie rods down a couple degrees) as it was under acceleration (tie rods up a couple degrees). We would have marks on our front shocks to tell us where the suspension was under braking and under accelleration. Pretty simple after that.
In r/c cars, you can use washers on the servo arm attachments and/or the spindle arms to adjust the angles of the tie rods.
