First of all, what type of website is it? If it's a business website, then you may want to use one that goes with what you're selling, so you'll want to use the SFI and TripleClicks. If it's more of a family or personal website you might want to target families, and advertise cleaning products, or health and wellness, pet products, etc...
You also want to take into consideration where you're placing the banner. If it's a small sidebar you might want to use a small 125 x 125 button or a vertical banner. If it's a bigger page and you have plenty of space, you'll probably want to use a 468 x 60 or bigger banner.
