Malzahar liandry's combo VS pen + rabadon

What do you consider the best thing to build on malz. Most of the time i find myself building pen and rabadons unless I am behind. But i see most malzahars go liandry's combo regardless of enemy team. Is liandry's always better? I tend to only do it if they have 2-3 (depending on threat) tanky champs. Otherwise i feel like pen and rabadon is much better for squishys. Am i wrong here?
