On a scale from 1 to 10, with 10 being the best:
I rate the Atlas CZ cars a SOLID 9. With a capacitor they would be 10's.
I rate the GGD El Capitan cars a very disappointing 3.
Both use LED's so the voltage draw in minimal.
The Atlas lighting soft and even throughout the entire car. No hotspots, no glare.
The lighting in the GGD cars is harsh. There are four hotspots per car and the ends of each car is dark and cold. This is really a shame since Scott put in such a solid effort to get detail of the interior so nice. If you get a chance to view the lounge car and coaches closeup you will see what I am talking about. But it is best viewed in natural daylight.
