Using tow/haul going uphill will often depend on someone's tolerance to noise. With the more aggressive shift points comes a higher level of engine noise within the driver's compartment. If you can tolerate the higher noise level associated with higher engine RPMs you will climb the hills faster and a little smoother. Going downhill the one tap of the brake downshift is, IMO, essential to safe operation and longevity of the brakes. Using the engine as a brake will keep you from riding the brakes and thereby overheating them on moderate to steep declines.

On flat land depending on the speed limit of the road being traveled I may or may not use tow/haul. At lower speed limits tow/haul may cause the trans to ride at the lower end of one and higher end of a shift point thereby causing numerous unnecessary shifts between gears. This is more common off interstate than on interstate. Within a city I generally turn tow/haul off if I am not towing.
