Which is better 1/4” or 1/2” insulation under the track for good looking ballast? I am using MTH Scaletrax.

It depends. 1/4" is a full foot and will be the right amount much of the time. 1/2" is two feet which may be too much next to an industrial building, but could be just right in other situations, such as out in a country scene. Or you could go with either one and vary the hight of the surroundings.
