The question is extremely difficult to answer actually unless you describe the vehicle's use and front and rear axle weights etc.
For example shockers generally are replaced along with springs. Springs provide ride height only and with differing heights to compensate for the weight you may be adding. Like a winch, dual battery system, bull bar etc etc at the front and storage system, long range fuel tank etc at the rear of the vehicle. All these things impact on spring height and strength.
Shock absorbers or dampers which is their correct term have only one function. To slow the bump (vehicle going down) and rebound (vehicle coming back up again) as it is impacted on by the road surface. Road surface ranges from bitumen to
rock, sand, corrugations etc. Dampers or shock absorbers do not control ride height the control ride comfort and should be matched to the correct spring rates and heights other wise you end up putting a lot of strain on all of the
suspension components. Your tyres also play a big role in
suspension setup as tyres with very strong sidewalls will impact on
suspension performance to variable degrees.
So what is a good brand of shocks? The set that matches your springs and vehicle needs. All
suspension is a compromise particularly on a 4WD where it is supposed to be comfortable around town and capable off-road.
Reputable brands from know suppliers who will back their product and warranty are the best choice. No brand in our experience is better or worse but then we only ever use three brands on our tour vehicles and all three have failed at some point due to manufacturing faults. But on balance we have run up several hundred thousand kilometres with only a few issues so I don't get excited about these sort of issues. But I do get a bit tense if I don't get the support I expect whhen things go wrong.
So in short speak to the suppliers and if they don't ask you any of the above questions about vehicle use, travel needs etc then you are probably in the wrong place.
Suspension setup is a highly person thing and what some folk will say is a harsh riding
suspension can be considered too soft by others.
For general information we have standardised our Prado's on TJM's XGS springs and shocks with
the springs being extra raised heavy duty as the vehicles have
winches, twin battery systems etc and weigh in at around 2940 kgs for a two week Simpson trip. Tyres are Bridgestone D694 and it works
well. On the other hand our shorty Jeep is on XGS springs and Tough Dog shocks and they really suit this light car nicely.
