This is an unexpected surprise. I hope it encourages more players to finally play the better KotOR.
I don't know how this is a matter of debate. Obsidian has a long history of favoring writing and by extent world-building in their design priorities. Even before the formation of Obsidian Entertainment a lot of their prominent employees have a strong reputation in doing so, notably with Planescape: Torment (MCA will be missed, but I hope his future RPG endeavors will put his talent to good use). Some good examples from Obsidian proper include Neverwinter Nights 2: Mask of the Betrayer, Fallout: New Vegas, and Pillars of Eternity. On the other hand, BioWare has never excelled at writing, even before their decline. I feel the reason they're often put on a pedestal is because relative to the standards of the rest of the industry, they stand out, but that's not saying very much.
