Those two are not nearly the same, and the TWH bit is harsher. Notice how the overall curve of the shanks on the pleasure bit is forward (towards the horse's nose). The shanks of the TWH bit curve backward first. Backward curves result in much more pressure than forward ones. The forward curve below the backward one is not enough to decrease its strength because it's smaller.
Shank shape from mildest to most severe: Strong forward curve, slight forward curve, straight, slight backward curve, strong backward curve.
If it really were just about the rider's hands there wouldn't be so many different kinds of bits.
