In my knowledge, there are some differences:

- in error reporting: type aliases may be replaced by their definition in error reporting.

- you cannot create union types with interfaces

- legacy versions of TypeScript does not enable to create recursive type aliases such as type `List<V> = {v: V, right: List<V> | undefined }`

- interfaces with same name are merged

However the frontier between type aliases and interfaces seems more and more blur. Generally interfaces are encouraged over type aliases. I personally prefer type aliases because there are more capable and seems more elegant to me. However their poor support in error reporting makes me rely more on interfaces when possible.

Yes the error reporting is why I prefer interfaces over types since a long time now. The definition is useless in many cases
