I personally don't like the amount of blue actinics put out. It isn't necessary in my opinion for your reef animals based on measurements I've taken related to photosynthesis. If you like a bluer tank visually, then get it. I prefer clear water and more intense color on the corals and fish rather than everything looking blue including the water. So I'm adding my own 55W 9325K PC into my custom fixture since I already have an existing 55W PC kit.
If you want to see what I mean by more intense color, check out this thread. Notice how more contrast there was and you can see the beautiful black angelfish so much better. Notice how colorful the dwarf gourami and red plants became. Notice how the water looks clear instead of yellow/greenish. In the last comparison, the black background actually looks black instead of a tint of green.

If you search my past threads, you can see photos of my tank with Actinics vs with the 9325k PC. You'll see blue water vs clear water.
I haven't received my dual 150MH yet but when I do, they'll have IceCap 10K on them. I can then see the difference with and without the PC. From past experience, having MH only didn't bring out as much intensity in color as having MH + the 9325k PC supplement.
