Rear main seal

I have to replace my rear main seal, does anyone know if there is a better replacement seal or just the same as factory?

Just for the record, OEM Z32 is really almost high end aftermarket in quality and performance compared to most other cars as the Z32 had a LOT of over-engineering applied to the car to make it more reliable what with all of the new (at the time) technology Nissan packed into it.
Unless specifically noted here for reasons of known failure or needed upgrade, Nissan Z32 OEM is nearly always the best way to go unless performance or some other reason takes you there.
