Advantages of Using Black Solid Vs Adjustment Layer for effect

This question comes in the setting of using After Effects as a host.

For using a rain overlay on a background…

I notice that I can apply effects (like BCC Rain) to a solid layer that is 100% black, apply screen mode to this or I can achieve identical result by just using an adjustment layer and applying the BCC rain filter to this.

I am curious is if there is any performance advantage/disadvantage of using one over the other.

Thanks in advance for any insight.
