Aurora is way better and it's far more stable it's also being updated so hopefully in the near future it will have everything that FSD has, and way more.
FSD is good but it's very laggy sometimes especially when you have lots of games. Plus FSD servers are down.
I still see many people still use it, but the end, everyone's opinion is different.
You can't just say Aurora is not good, it's like insulting the team who made it. I'm not a developer, but I know it's not easy to make a dash like Aurora.
