vehicle question

I replaced the headlights in the wife's car this summer with silverstars. Christmas eve the drivers side bulb burnt out already. Walmart was still open so I just grabbed an $8 bulb and installed it. Driving home on a dark highway the next night I noticed no further distance or brightness from my silverstar bulb compared to my new cheap Wamart bulb. I don't know if I should be disappointed with the silverstar bulb or be impressed with the cheap bulb.
