Based on what criteria?
The HRAP VX has all Sanwa parts. The FS VX has all Hori parts, but is super easy to add Sanwa/Seimitsu parts in its place (well, Seimitsu buttons. I dont know about Seimitsu sticks in teh FS VX)
HRAP VX is a bigger, solid stick with a cord compartment. FS VX is a smaller, lighter stick, no cord compartment.
HRAP VX has 8 buttons and start just to the right of the buttons. FS VX has six button and start is up top next to Guide.
HRAP is an out-of-the-box better stick for durability and build quality. FS VX is is lighter and is, to me at least, the second coming of the Namco stick.
