I did a test this morning to compare my Power Fusion (my shaver of choice for my face) to the HeadBlade. In my opinion the HeadBlade is the clear winner. It was smoother with the HeadBlade and I did need as many passes over problem areas.
I know that some here prefer the Fusion or other handled razors, but for me and my dome, I'll be sticking with the HeadBlade.
The "HeadBlade rocks my dome!"
