are rear adjustable shocks worth it ?

i have now k-member upper and lower a arms qa1 shocks elibach springs bmr torque arm adjustable rear bmr lower control arms. are the rear qa1s worth it or should i go with a different shock ?

I have the Hals in the back. I could tell after i put them in. I have not played around with the adjustments that much. The factory shocks suck.

I have c/e's in back and I'm about to order qa1's for the front. Hope it's a good combo.
