The DOT 4 is better because it has a higher wet boiling point. While both are good, brake fluid absorbs moisture like no other fluid out there. The wet boiling point determines how hot the fluid can be before it breaks down and stops doing it's job.
Brake fluid is subjected to very high temperatures, especially in the wheel cylinders and disk brake calipers. It must have a high boiling point to avoid vaporizing in the lines. This vaporization is a problem because vapor is highly compressible relative to liquid, and therefore negates the hydraulic transfer of braking force, so the brakes will fail to stop the vehicle.

I liked the ATE SuperBlue, but DOT recently outlawed it because it is not clear or amber...
I know, but I liked the blue!! Makes it easier to tell you have the old fluid out when you are flushing it. Plus I think the DOT ruling was dumb.ATE TYP 200 - same as Super Blue, but clearish/light amber
