Shackle Lift or AAL question

I'm confused on which will ride better and give me more off-road capabilities. It would either be a 2" AAL or a 2" adjustable shackle lift. Both are wheelers off-road brand.

 

probably the shackle depending on how shot your leaves are. the AAL will stiffen the ride and the shackle shouldn't change much but will increase articulation.

 

The leaves aren't sagging, the trucks at 128k. I was also thinking of a AAL and shackles for a full true 3". Would that level it out if I got 3" eibachs? I was also thinking of getting a whole new leaf kit because the squeak just make me cringe.
