Benefit is....you can change the bars stiffness because it has 2 slots on each side of the bar, so you can choose the furthest slot for less rigidity, or closer in for more.
As someone who doesn't track the car, an "adjustable" bar is useless to me. Why on earth anyone would want an adjustable bar I don't know, but I'm sure there is a reason to some people, although I personally can't see one.
Cusco sways are not adjustable, it has one setting and that is all that you need.
Whiteline is one manufacturer of adustable bars, but not the only one.
Adjustable bars aren't something you'd generally adjust regularly - they do give you more flexibility (wrong word in this context perhaps! :p) in terms of what you get for your money.
If you buy a 22mm fixed bar for example, you're stuck with the setting as it comes from the factory. It might suit you perfectly - in which case, well done. But an adjustable bar gives two settings that you can choose from. You might buy a 21mm adjustable bar, and on the loosest setting, it may behave more like a 19mm non-adjustable bar. On the tighest setting, it may behave more like a 23mm non-adjustable bar. So you get a bit of "play" in how you set the car up to suit your requirements. And some adjustable bars have three settings - the middle one is roughly the equivelent of the same thickness non-adjustable bar, and then you have one setting which is stiffer, and one setting on the other side which is not quite as stiff.
Also be aware that just because a bar has a given thickness (let's say 22mm), not all bars of that same thickness will behave in exactly the same way. A 22mm bar from one manufacturer may be harder than the 22mm bar from another. The material used, the profile of the material (solid, hollow, if hollow, how thick are the walls of the tube and what shape is the tube) all have an impact - the shape of a solid bar can have an impact too (if it's not a uniform shape, it will be stronger in one direction of flex over another - a flat bar is strong in one direction (side to side along the width of the bar), but weaker up and down.
