I bought one and prefer it over the standard. I was told it was cut smaller, but laying one out on top of the other I can find no difference.
Being able to furl it allows you to depower and might make beaching easier for you. You can also adjust how much you have out, if you still need just a little to help to turn the boat in tight docking situations.
I like mine a lot and no longer bother using the standard jib. The furling unit is the way to go, in my opinion.
