I'd say at that price point it is mostly preference. I have a set of Hella 500's on my Suburban, and they are fine for what they are. They aren't super bad desert racing setups, but they light up back woods roads and mountain passes when I need them. I put them on mostly because they were disposable, and I wouldn't have to worry about them being stolen.
I Run KC's on my Wheeler, and they are great as well. Similar light output, but a metal body, which makes them a little more durable.
