First things first......are you forging? Or will the blade be a stock removal? This has a great deal of impact on how these two steels will perform! Some may argue the point, but I've done the "homework", and testing to verify this. A stock removal blade of either with "standard" heat treatment will perform no better than a blade of 10 series steel with the same heat treatment. Where you will aquire the performance is in the thermal cycles of the multiple quench process. Forging will create the grain flow, normalizing and annealing will refine the grain structure, and the multiple quench will further enhance the blade's integrity.
Either will make an excellent camp type blade, but 5160 will give you more leeway during the process. It is more forgiving of mistakes than 52100. On the other hand, 52100 will make a little better blade, but you must be "dead on" with your handling of the material. 52100 won't tolerate overheating, and unless you feel confident that you can "nail" each and every step of the process, 5160 is your best choice. In the end, it all boils down to the makers familiarity and knowledge of the chosen steel, and the ability to get the most out of it.
Good luck!
