I watched both versions and preferred the Korean one (though I loved Simon and Kate's house more). The World of the Married tones down the sex and amps up the Greek chorus element (the Gosan women's association). The Korean version does a better job of creating an oppressive environment of stifling conformity and pettiness within the hospital and the city's elite that better explains (but does not justify) the couple's actions.
In Doctor Foster, it is all Suranne Jones all the time. Don't get me wrong - she's an amazing actor. Kim Hee Ae is a different kind of actor, more understated, so her actions come off as more shocking. The son and the other side characters (yes, the children are secondary to the twisted couple), are also fleshed out better. I understood the neighbors better, and their relationship trajectory was quietly devastating. There's an additional plotline involving a younger couple ensnared by the main couple to carrying out their revenge. Melodramatic and heartbreaking on its own. There's more of an emotional investment overall with the Korean version.
K dramas are known for how much their original soundtracks (OSTs) add to the storytelling. The World of the Married is no exception. I can still hear the violins in the minor key. Also, the fashions are yummier.
