NGK's. Although the spark plug part number will differ depending on your set-up.

Don't use Autolites. They have a history of breaking apex seals. At least several people have claimed that's the issue. Apparently some of the Autolites stick out too far and chip the apex seals as they go past. Just get NGKs and be done with it.

Nippon Denso is what came in the engine from the factory. Some members don't like them or claim to have had issues with them. I've found either NDs or NGKs work fine. I even have some Autolites in my collection and they have worked fine. There are some Autolites that are too long and will chip apex seals.
