For me WOTR is much better. I like mechanical complexity, mythic paths are very fun and actually influence the plot and the ending. Overall plot was complete enough for me on release and didn't suffer from "this companion is written so bad I'm gonna wait for EE". Main story is more reactive to the player.
It isn't perfect either. The game was and still is ridden with bugs and some endgame mythic paths are lackluster. But I had more fun.
