I believe you are asking "are aftermarket sway bars worth it?" .
IMOHO, not yet. Sure I have had them in the past, on my Zephyr, and they were cool in that they were adjustable. My friend currently run MM stuff (but he's just weird).
I dont, and wont for a looooong time. Not worth it (yet). Most systems (Griggs/MM) are designed to work with the stock stuff. You are adding more complexity to the equation without know what that will do.
Someone wanna prove me wrong, go ahead. This is just my opinion.
