Easily Underrail. The combat is objectively better, the game runs and feels much better than AoD as well just in terms of performance, graphics, and UI, and the overall ambiance and story of Underrail is honestly one of the best out there. I haven't managed to fully commit to an AoD playthrough because every time I boot it up I just feel like closing the game and doing something else, but people who enjoy Underrail cite it as one of greatest RPGs of all time, while people who enjoy AoD don't tend to think of it as highly.
