Crimping ignition wires is a big pain, and you need special tools. You also run the risk of screwing up, and since Murphy's law applies so well to working on cars, you probably will. So, unless you plan on making custom sets for all your cars, and all of your friends cars, it's just a big waste of money.
I personally like the Magnecor 8.5mm Wires. They perform well, look awesome, and are very well made.
NGK is a good stock alternative, but for big power, get the Magnecores.
