Pc is the way to go.
Bugs and issues can be worked around via the console in game which is not possible with the console version.
The above mentioned should be the major contributer to his choice.
If he has a pretty decent pc, the graphics at max settings look a lot better than they do on console.
Besides games like Witcher 2, Oblivion, Skyrim are meant to be played on pc, I remember buying and playing oblivion on console and I hated it so much!!
WASD CLICK CLICK FTW!!!
