The culture path definitely feels more diverse, even a little dynamic now, but I think it now exposes how blisteringly fast the Modern age is. Before the culture victory change, I'd usually get that or economic first; now that it's slowed down, I find that science and economic are the fastest and most natural, easily achieved before half of the age has gone by. Economic stands out especially badly now: the conditions for winning it, essentially, are established in the earlier two ages with the resources you acquire; in Modern borders have become more solidified and there are fewer empty spots on the map to settle, meaning an economic victory more or less amounts to getting rail stations and factories, then sitting on what you have. It's not a very active path to victory at all, which is a bit disappointing considering how interesting the Monopolies and Corporations mode was in Civ VI, and how it was geared towards not just controlling an amount of a resource, but having a monopoly of it. That's what the economic victory should be about, no?
I actually think cultural victory is in a good spot now—just the rest of the Modern age has to be brought into a more coherent order and expanded. There could and should be at least two more tiers of techs and civics, giving the whole age more room to breathe. The much-maligned slow pace of the ideology/domination victory path, I think, should be the norm rather than the exception.
