I'm middle of the road on this one. LEDs are okay. Actually, I think Cadillac does a great job of how to integrate and use lenses with them. But I wouldn't think twice on them when thinking of buying the car.
As far as superiority, I don't necessarily agree they're better in every aspect. The recent wave of changing all streetlights across the country to LED (Boy would I have liked to have been the one writing that contract) improved light visibility and rate of light response but darn if you don't already see some with parts of the grid burnt out. I'm not convinced they're as hardy (yet) as some of the old incandescent housings.
