Default Spark Plug choices for 997.1s

Curious as I know the oem plug replacements are the Bosch with 4 electrode pattern. I see that NGK also has one with similar electrode pattern which is listed as an oem replacement. Curious if there is any difference between the two.

The Bosch plugs work very well and are relatively inexpensive.

I just did the NGKs today with new coils, the NGKs are around $2 more per plug. They look to be better made than the Bosch ones, not sure if they have any performance difference.
