ASF-Achievement-Manager VS resharper-unity

For example, https://github.com/Ryzhehvost/ASF-Achievement-Manager

You can indeed do that using this plugin

Best explaination I've found. Use CompareTag instead of explicit string comparison · JetBrains/resharper-unity Wiki (github.com)

I'm a huge fan of the safe navigation operator, but I'd be remiss not to point out that it doesn't work with any references derived from UnityEngine.Object. See for more info: https://github.com/JetBrains/resharper-unity/wiki/Possible-unintended-bypass-of-lifetime-check-of-underlying-Unity-engine-object

FYI it is bad for performance to do null checks on any unity.engine objects: https://github.com/JetBrains/resharper-unity/wiki/Avoid-null-comparisons-against-UnityEngine.Object-subclasses

However null checks for Unity objects are slow compared to standard C# classes, see this link for a brief explanation, there are also many discussions about this on the Unity forum. Not sure though, if that is still true for recent Unity versions.

The fact of the matter is as a primarily C# .NET developer you have all been polluted with bad coding practices from tutorials and partially on Unity's end too. For example non preferred method of using the null-conditional access operator.
