Theres the thermal efficiency which is its own argument. I'll instead address all the other stuff.
Plenty of vehicles don't have fluid passages for a trans cooler. Some was an option, others were HD use only...and plenty had M/T. If you want to run without a dedicated trans cooler, you'll want a place for it in the rad.
The AD and earlier rad's would be too small for most of the cheaper large diameter electric fans, so to run 2 fans, your going to the smaller units (they still work, but not everyone wants to spend the extra $ for that, just to retain an old rad style, if they have to buy a radiator anyway. )
I'll be vain and add that copper is kinda ugly under the hood if the style doesn't fit the look of the truck/engine.
Aluminum is also strong, light, and easy to repair (more guys know a TIG welder than they do guys with brazing skills)
