Yeah I prefer 6 over 5 any day, but there are a few small things that 5 does do better imo. I do prefer the more serious art style of 5, and I noticed that there is a lot less actual dialogue in a civs respective language compared to 5. While I do like automatic road creation, I do also miss being able to build it manually to have more control over where units can go. Finally, I think the happiness system in Civ 6 is a bit too easy, as it can be mostly ignored and very easily fixed compared to 5. Keeping your citizens happy was much more of a challenge there.
