I just went through this very dilemma this spring. I went with viking double adjustables, 19 rebound and 19 compression adjustments separate from each other and the car rides better than ever. I opted for the warrior valving in the shocks instead of an upgraded valving option that is available. The qa1's were 200ish dollars more for double adjustables like these. I have only put like 100 miles on it because I wanted to do the rear as soon as I finished the front...should of just bought the whole kit right away. The monte has tubular a arms upper and lower and with a big block with aluminum heads and a 4L80E trans. Ride height is higher than the old (original small block) springs and shocks with BMR arms but livable. I went with 550# springs in the front and 125# in the rear. In the picture fronts are almost all the way adjusted down and the rears are about 3/4 of the way up. The vikings mount in the original spring pockets in the front as well. I only regret the 550# springs (followed the buyer chart for spring selection and I figured I would need the big block spring but looking back maybe a 450 or 500# would be better), in the front because it is at the bottom of the adjustability for lowering it but it is also easily solved. Hopefully a person with qa1's can give you the pros and cons of that. Hope this helps.
