My 2012 Mustang has the standard headlights. Didn't want the extra cost (originally and repairs) of the optional HID's.
I read the current version of this site and also emailed Mr. Stern. His responses basically summarized the web articles. Nothing new/different.

There is no other type that will fit and work. Each headlamp must use the type of bulb it was designed for. There are a few cases in which a different type of bulb can be substituted, but they are a tiny minority and none of them involves a 2-filament bulb such as H13. The best H13 bulbs presently on the market are the Philips Xtreme Vision items:

items:
http://www.amazon.com/dp/B00480KPLWDo not buy blue or "extra white" bulbs (Silver Star, Crystal Vision, Hoen, PIAA, etc.); despite the heavy advertising push and claims of "brighter and whiter" light, they actually produce _less_ light due to the blue glass they use. Also, "HID kits" in halogen-bulb headlamps or fog/auxiliary lamps (any kit, any lamp, any vehicle no matter whether it's a car, truck, motorcycle, etc.) do not work safely or effectively, which is why they are illegal.

"Slightly" is the best you can hope for.
Bottom line. I see no point in changing bulbs since any improvement over oem would be minimal unless the old bulbs are tired. Read the articles for details.
