Most common manufacturer who make plug are NGK, Denso, Beru, and Borsch.
Nowadays the hottest plug in the market are Iridum plug. The reason of using Irridium plug are the resistant of the plug are much more longer than platinium. An Irridium plug can easily last for 60, 000km and some many experience use up to 100, 000 km. Also the power require to work on Irridium is lesser than Platinum Plug.
My personal has used NGK Irriway and Denso Irridium. Both performs similar performance and durability. However, I prefer Denso Irridium due to the Irridium size is only 0.6mm which draw power less.
There are some different point of view of using plug. In Asian country including Japan, they prefer Irridum but in America, they have different theory to explain about this.
