Suspension is the single most important system on a vehicle, short of brakes. A proper set-up isn't cheap. I can go on and on about shocks and tell you why they matter more than HP or any other consideration, but I won't...
Instead, check this out. The info presented here will be that much more relative if you know exactly how long your shocks need to be in the compressed and extended lengths, and for what type of "ride" you'd like them tuned. Plan to spend some time looking through it...
If you find something close but not quite right, remember that your shock mount points can be re-positioned using readily available aftermarket mounts.
(I suspect, based on you blowin' all four of your shocks at the same time, that you didn't have the appropriate shocks/mounts for your application.)
Bilstein generally offers two ride characteristics in their rebuildable shocks. AEV and others give airs of propriety when they sell you their "special valving". It's nothing special, Bilstein can do the same for you if you know what valving you want by way of the individual shims, etc... (Not trying to sell you on Bilstein, just sayin' what's possible with some shock MFGs.)
Otherwise, you could get them to set up a shock based on your ride preferences. IIRC, the two valvings they typically offer are described by their ride characteristics, briefly, somewhere in this document.
As a side, I've haven't bought the shocks for my, as yet, uninstalled lift. When that time comes, all the measurements will have been taken and any need for alternate mount points will be accounted for as will any "want" for fully adjustable, rebuildable shocks...$$$.
Bang for the buck? Cheap shocks = cheap ride, reflecting on the overall vehicle package.
I think you should spend at least as much on shocks as you do for tires, and that's a minimum.
