This is possibly getting off the original subject, but in my maybe limited experience of Cat C airports it isn't about one pilot being better than the other, it is often down to training costs.
To take the example of VNKT which is what the thread is about, the simulator training takes about 5 hours, most of which is devoted to the circling approach and the single engine go around from various points in the valley.
The captain is designated as PF and does the flying, most of which is hand flown.
Halfway through the detail it is normal to switch F/Os, as they are not PF, so they spend half the detail as PM and half observing in the back of the sim.
If F/O s were also checked out as PF it would double the cost of training in the sim, and also need more line trainer's time for the initial airfield visits.
Strangely enough, in all of the times I have flown into VNKT none of the F/Os, ranging from 300 hour cadets to 10000 hr ex turboprop captains, have expressed any regret at not being allowed to fly a steep NPA, with a tailwind, at night, to an upsloping runway in a black hole surrounded by 15000 ft mountains. There are plenty of other difficult places on the network that they can fly to if they feel a need to prove themselves.
