There is a lot more to how effective a round is than it's velocity. It's also important to know how well a round penetrates, expands and retains weight. Sometimes a round tha penetrates barriers is desired, sometimes not.
HydraShok is a very old design. In its day it was state of the art, but today there are vastly superior rounds, like Speer Gold Dot and Federal's Tactical line. Also, the Winchester RA9T is among the very best available.
The issue with HydraShok is that the bullet is not bonded to the jacket, which hinders expansion and does not prevent fragmentation.
That said, I have no idea what the "low recoil" aspect does, but I prefer to go with rounds that perform well in lab testing (as opposed to "street testing").
