I'd say the best for me was inquisition.
I much preferred the more 'renaissance' feel of the design. Its quite refreshing to not have a Medieval RPG. Also the architecture was, whilst not always pretty, was interesting and different. I loved the grass roofs of Ferelden, and the Giant metal spikes in old Tevinter forts, I liked that because whilst it wasn't realistic compared to our world, it makes sense that, especially Tevinter architecture, would have a lot of things which wouldn't be possible in our world because they have magic and enchantments which keep the walls strong.
I think I also liked DA:I's art style better because it was brighter (and i would argue its not any brighter in most places then the real world is), I like thats its not all dark and gloomy, because things dont need to be dark and gloomy and **** like that to be cool.
