Definitely whiter and brighter. Getting flashed by oncoming vehicles? With the brighter bulbs I put in I get flashed once or twice a night. The cut off line hasn't changed it's just brighter but the stock bulb was a joke to where people riding with me would tell me to turn on my headlights. Would like to compare the H9's I dropped in to the LED's and see the difference. The longevity of the LED's would be worth it if they are at least comparable and a no brainer if they are better.
