Every OOP proponent has a different characteristic of what OOP is and what it does best. I *have* heard claims that OOP is "better at building large-scale software". (Although, I think one-big-exe is a design smell, but that's another debate.)

As far as decoupling, I've yet to see examples from my domain that don't make suspect assumptions about change patterns/frequencies. (I cannot really evaluate the change pattern frequencies from domains I am not familiar with, but usually spot potential tradeoff decision paths that don't seem to be documented and compared well.)
