I've been using them for about 4 years now (previous and current generation). Yes definitely much brighter and I swear by them. They have a short lifetime though so if you find it hard changing bulbs in your vehicle then I don't think you'd want to use these. Mine tend to last for about 15 months. If you want something with a longer life try the Osram Silverstar bulbs - they are brighter than the standard bulbs but not as bright as the Night Breakers.

In my experience replacing the standard H7 bulbs on my E82 BMW, the night breakers don't seem to increase the range of the beam and instead give more of a blue colour. Sadly I think they make it look like you have a set of knock off xenon lights but without the glare. If you want that type of look then they're fit for purpose. I would recommend the Philips extreme white bulbs as I think they did actually improve the range and intensity of the lights, removing the yellow of the standard bulbs without introducing any blue hue to the mix.
