There is one condition in which the PG is more satisfying: kicking down at (roughly, depending on the application) 50 mph will engage 1st (1.82:1) and accelerate better than the TH which can only catch 2nd (1.52:1), so torque multiplication is 21% higher.
Of course, below that speed the TH can reach 1st, and above it the PG has nothing available except high gear.
