I've always tried to be cognizant of my placement over rocks along that area and haven't had a problem in all these years. The bolt in ones seem seem simple enough if they will provide some extra protection.
The weld in ones from Clayton move the lower shock mount behind the LCA mount which protects it better. Some where on this forum I have a write up of the installation.
I had the Currie extensions as you note above, only made the problem of bending the lower shock mount worse. IMO, bolt on are a waste of time and money.
As a result of the Rubicon rumble, had to repair/replace the lower rear shock brackets as they were "hammered". So, you plan a couple of hours with your son who you bought the welder for and: Remove the old brackets, clean it up, weld in the new, paint 'em, bolt up the shocks with a little...
It feels more planted and smooth. Like going over the same stuff that would rattle it around and make the jeep jittery is a lot more smoothly absorbed. The little stuff and ground irregularities and water drainage cuts on normal dirt trails could be taken faster or a similar slow speed, but not be punishing. The bilsteins just seemed a lot stiffer in every situation and every little imperfection in the road/ground was very much felt.
