Indeed like every other Pajero said, I do agree 2-3 inch lift is good and sufficient for offroading.
Also, Ren13 comment is for extreme cornering like roundabout at 80 and above, he is an ex-corvette guy lol. For normal road user and if you are driving the same 4x4 from some time, you will not feel much difference in cornering tbh.
For Pajero most important offroad mod is the reinforcing the rear bumper with a solid metal plate to avoid scooping the sand which results in breaking the rear bumper within a couple of drives.
Old Man EMU VS Ironman is a tough call but can be decided based on the product you put your hands on. Old Man EMU being quite old and offer a reasonable mix of comfort for road + firmness for offroad as oppose to Ironman that is more oriented towards offroad means you will lose road comfort more unless you choose their adjustable shocks (if they have), which will be eventually more expensive.
