I'm not the expert, and I don't have a set of Truck-Lite's to personally compare. @slantsixdan puts the JW Speaker headlights as the best "by a big, big margin" even compared to the truck-lites, and he is the expert.
The way I look at it is this, every foot you can see further/better is a foot faster you can stop/avoid when you see that thing you're going to hit. Sometimes hitting something and missing it is determined by less than a foot. What's that worth? A small improvement in vision can make a huge difference in the outcome. I drive in the dark quite frequently, as I said before several months out of the year for like an hour at a time every week or more, so for me I wanted the best. If you've got a weekend car you only drive in the daytime then the headlight lighting isn't nearly as important and I can understand not wanted to spend $366 on a headlight. But that's a **** load cheaper than hitting a deer and having to repair the damages.
For me I think they're totally worth it. But I wouldn't say they're right for everybody, like pretty much every modification to any system on the car it depends on how you're going to use the car.
