Default BAD Roads Bilstein5100 vs RS9000 Rancho

Daily drivers are all half ton 4wd, torsion bar rigs. Two stock height, one 5 inch lift.
Roads here are chewed up bad, broken pavement, huge open holes, and gravel roads are basically long piles of softball size rocks, graded with a crown.. We use up shocks fast around here.
Which will likely give the better damping ? Rancho RS9000 or Bilstein 5100 ?
Which is likely to last longer ?
How's the warrantee service with Bilstein these days ?

I use Bilstein 5100 shocks on my truck, I love how they handle rough terrain, I have at least 130,000 on em now and still going strong. I don`t know about the warrantee to be honest but I have had no problems. Hopefully they are still will made and not china junk.

5100’s for everything from the family cruiser to the off-road truck.

Worn out 3 sets of Rancho RS9000- They work great for 6 months to a year... then lose REBOUND damping entirely. so far waranteed service on 6 units, but getting old.
Bilsteins doing well on Wife's rig, but smoked 2 pairs on front of Tahoe. again, first they lose rebound, then compression fades.

. Who makes BETTER shocks that last a LONG time on very rough roads ? Most speed limits low here. 45 mph and 55 mph paved roads in my area.

Anybody here?
This forum is awful quiet.
WHO MAKES BETTER OFF THE SHELF SHOCKS for stock height road use on a GMT800 chassis?
Bilstein's 5100 were my old standby...... newest versions are not holding up well.

I don’t have anything stock on a 1500 lol

However, I do have Foxes on my diesel and I like them so far.

Local parts house ( Oreillys) waranteed another set of Rancho RS9000, so the lifted rig is wearing Rancho again, 3rd complete set in less than 25,000 miles.

3 other rigs PAVED road service are still wearing Bilstein5100: Had two sets waranteed- must have had some QC troubles with Bilstein, hopeful these will hold up longer.

In theory, my ROAD vehicles should not be too hard on shocks, the Bilsteins replaced 18 to 20 year-old OEM SACHS, which were still working.
