Default Best Spark Plug for SC400

Quite simply put, I want to know what the best performance spark plug is for the SC400, specifically a 98 with the VVT-i.

I have searched and search and see a lot of recommendations for the 300, and some debating and arguing over pros and cons, but longevity and cost aside, what is the best spark plug to use in the 1UZ-FE VVT-i from a performance aspect. And what if any data do you have to back up your claims? Also is the stock gap (I believe 0.044") the best gap to use, or should I go with another gap size?

I'm running Bosch Platinums in my '92 SC4. They work and will keep working for 100k miles.

Keep the stock gap.

Stock plugs are most likely the best.

Esp if the car is stock then there is no need to mess with plugs or gap.
