Either would work. Hydraulically, they are the same. It just depends upon which is easier to connect. You could also completely eliminate the tubing along the subframe rail and run hose all the way from the heater core outlet. Another option would be to use a coolant return tube from an earlier ThirdGen that did not use a heater control valve. There was no valve at least through 1986 models.
