As far as I know the Linglong is the just a mini version of the Aurora. But I do know for sure that the Aurora is basically just a Florian modded Wind. So therefore the Aurora is newer and better. I think it is one of the most overlooked speedcubes on the market actually. You would really like the Aurora. The Wind is not that good though, it feels nice, and isn't a bad option for beginners, but there is absolutely zero reverse corner cutting.
Summary, Wind = Bad, Aurora = Good, Linglong = Small. Happy cubing.
