If I were in an actual wilderness survival situation 'd much rather have Cody Lundin along that Bear. Cody at least is mildly amusing. Bear would be trying to sell me all his officially licensed products andI tend to find the man generally annoying.
I would take Les Stroud over anybody. Mr. Lundin offers a lot as an author and presumably as an instructor, but I respectfully disagree with him on the footwear front.
As for Mr. Grylls, I expect that if you were in an actual wilderness survival situation with him he'd offer you a meal from craft service and give you a ride in his helicopter to a nice hotel.
