Hori differences

Here are a few really common sticks (none of which I am purchasing):

Top: looks like my current PS2 Hori stick. Nothing special, but has lasted for years.
Middle: Real arcade pro? Sanwa or not?
Bottom: Looks like middle one, but just for 360

Hori also has the Soul Caliber themed, SFIV themed and a BlazBlue editions coming. Many mods made to them (posted in SRK), but I’m more curious the differences between them (if there are really any).

The fs3 is all hori parts while the hraps have a sanwa stick with hori buttons. The differences is just the size,weight, and the hraps use quick disconnects that allows for easier modding.
