Any dual wipe socket will do and it is what I recommend. Avoid machine pin sockets. Yes they're considered 'military grade' components and are touted often as being more reliable but I feel that philosophy ignores real world application. The Sharp TV board's not getting subjected to the high vibration environment of an armored personnel carrier.
The legs of the NES CPU and PPU are flat, which a dual wipe applies more contact to than a machine pin and its round holes. Dual wipes have a higher success rate of remove/insertion cycles, plus machine pin sockets are brutally difficult to desolder if you ever wish to remove them.
