I tried the Xbrite first. They have a nice construction, but they didn't fit properly due to the lenses being misaligned with the housing. Ordered two sets. Same issue with both. Then i tried the Gem lights, and while they fit well, and the light patter was good, the construction was pretty cheap. Both of these required resisters to avoid hyper flashing. For which I made a custom harness to avoid cutting into the OEM harness. And I am glade I did. Because, these J.W. Speakers allowed me to forego the resisters entirely. And honestly, these are better quality than the OEM lights were. Very satisfied. That said, they are a bit over priced for what they are. But, when you factor the cost of the other lights, plus the resisters, and the quality improvement, they aren't much more.
