Oar rigs are not as nimble, putting paddlers in the boat is like going from 2 wheel drive to 4 wheel drive.
I'll chime in here as someone who has guided Class V both in oar rigs and paddle boats from The Upper Gauley in West Virgina to the Nenana in Alaska commercially and privately. Oar rigs can certainly be more nimble than paddle boats. However that is a simple statement that doesn't account for several variables like boat size and type, weight (gear, people and the boat/frame), and speed of the rivers currents. It also doesn't account for differences like hole punching ability vs ferrying ability vs turning speed and precision.
The key thing about Pine Creek ....it's a class V but the swim is Class V++. On the other hand there are about 5 Class V rapids on the Upper Gauley...but none of the swims on the Gauley have anywhere near the consequences of Pine Creek.
The swim in Pine Creek isn't class V++, it's class V. Class V swims are serious and not to be taken lightly. Appropiate clothing for the water temp, a PFD and a helmet are vital. Even at higher flows there are a lot of rocks you can hit on Pine Creek besides the hard stuff in an oar rig.
Swimming on the Gauley, especially in Lost Paddle, is also quite serious due to it's length, undercuts, water volume and sieves. Other spots on the Upper and Lower Gauley offer easier rapids with potentially deadly swims due to undercuts and sieves - Conestoga, Shipwreck and the far right side of Pure Screaming Hell come to mind among others. It is my belief that some of the swims on the Gauley are more consequential than those found on Pine Creek.
