I had a great time on this trip, with a few caveats.
The first day was the toughest. The stagnant, frigid pools were relentless and did not let up until the Middle Trail. Like CanyonMan said, the pools and the unending twists and turns create a huge drain on morale. By the time we reached the Middle Trail, we decided to camp, just so we could recover our spirits. However, there is a nice little stone bench elevated about ten feet above the canyon floor across from the Middle Trail where we set up camp. There's no water whatsoever, but we brought plenty with us.
The next day was much better. There were hardly any pools and the hiking went much faster. The boulder jam wasn't too difficult to overcome with rope. We initially missed the dropdown point and were searching all along the edge of the thirty foot drop thinking it looked nothing like the explanation in the guidebook. But then we turned around and saw the old ropes leading through a hole behind the large boulder. It was enough to get down.
Shortly afterwards we hit the confluence with Paria. The immense height of the walls was spectacular, and the hiking remained easy even though we were wading in the Paria most of the time. Unfortunately, the walls begin to quickly descend and the canyon widens out, losing its uniqueness. However, there are still a number of interesting rock formations in the canyon walls until it finally opened up right before the White House trailhead.
All in all, the scenery in Buckskin was incredible. Around every corner came something new and interesting, whether it was shafts of sunlight unexpectedly penetrating into the depths, creating beautiful pools of light against the canyon walls, or the interesting fluted patterns carved into the walls when the canyon was at its narrowest (little more than three feet). It was a surreal experience unlike any hike I have ever done. I highly recommend it, so long as you’re mentally prepared for it.
