I've watched reviews on several led bulbs all performed in the same manor, through the same housings (reflector and projector) that will prove that narrative false. As such, there can be tradeoffs and some bulbs are much better than others. However, the vast majority of decent led bulbs do provide an upgrade over a standard halogen bulb, and it is measurable and quantifiable.
The problem is that LEDs are not sending light 360 degrees like halogens and HIDs. Even if you get LEDs that can rotate for best output, the parts that block light affect the light output. LED bulbs are superior to halogen except for this problem. This is why you need projectors designed for LEDs. Without this, it will seem brighter (and it is), but will not be much, if any, improvement in important parts of the light pattern.
LEDs in LED projectors > HIDs in HID projectors > HIDs in halogen projectors > halogens in halogen projectors > LEDs in halogen projectors > halogens in reflectors > HIDs in reflectors > LEDs in reflectors.
