Go with the stock plugs. Different ones won't produce more power on their own.
Personally, I prefer copper because they burn nice and hot, are reasonably priced, and are easy to change.

My 03 owner's manual calls for Iridium NGK IGR7A-G's. They run about 50$ for 4. Yikes. I usually get NGK BPR-7ES's. They're copper and usually run about 14$ for 4. Never had a problem and more affordable. I just usually have to check and/or adjust the gap. No biggie.

Iridium will last longer than copper in a clean engine. Copper fires better in an engine that is older and uses a bit of oil but you need to replace more often.

Copper is always a better conductor and worth changing more often, IMO.
Unless, our cars need iridium for a specific reason, that is. I have a IX, so I also have no choice LOL.
I use copper, when I can (in other cars) and haven't noticed any downsides.
Cliffnotes: just go OEM if you don't want to worry about it. They last forever so, that's a bonus.

I bought 4 Champions at Walmart for my 8. At the time they were 95 cents each. The car ran fine.

First no plug is going to give you more power. Now that this is out of the way you should ask yourself these:
1) Will I be keeping the car stock for a while?
2) Do I want to change the plugs every 3k, 25k, 50k?
Personally I would run stock, my second choice would be iridium.

I would definitely recommend the NGK they work well
