LEDs aren't going to be brighter than the stock bulbs. And unless you install the HIDs properly into something like a projector housing, you won't get better performance out of those either; certainly not from the stock reflector housing. Your best way to go is shop around for the same bulb type and look for the best manufacturer and brightness/color you want. There's a lot of threads on here discussing bulb types and plenty of pictures showing the brightness and color difference.
