Spark Plug Options

What is the difference between these plugs other than the mfg/price.

NGK R Part # 2647 {Laser Platinum Plug #PFR5G11}
Twin Spark {.039 gap} @ 10.75 (Stock in my 01 E55)

or

BOSCH Part # 7422 MB# 004-159-19-03-26
Spark Plug; Platinum; Standard Electrode; OE Plug
16 per engine Updated version of OE spark plugs F8DPER and F8DPP33. Pregapped for normal usage. @ 4.46

or

Should I go Iridium?

I am ordering Magnecor wires and need plugs. Any thoughts?

Thanks.

+1... This question would also help me because I'm going to give my baby a full tune-up. Is a spark plug just a spark plug? Or they are all different, and can you feel the difference?

I've read Iridium plugs are good but really expensive and don't give anymore if any hp. From numerous recommendations I stuck with OEM Bosch Plats and they're going in next week with the Magnecor wires. Just my $0.02...

may be it will sound stupid, but European cars work better with european companies, so Bosch, and JDM cars work great with DENSO and NGK plugs. I would pick Bosch.
