Default spark plug question

Did a search and didn't find anything too specific. I will be moving up to LG Super Pro's in the next few months. I know that I should run the Z06 iridium plugs due to heat.

My question is what brand should I go with?

I know that a lot of vendors sell the NGK plugs with their header kits but have also heard the AC Delco plugs are just as good. Hoping that someone will chime in who has had experience with both.
