Currently the @typescript-eslint/prefer-interface is part of the recommended rules as an error. I believe the reasons are dated and in most cases types are just as capable and more flexible. There are a few cases where interfaces are better but I would not recommend them as a default. Therefor I would recommend removing this rule as a recommendation and just allowing users to configure it if they really prefer to.
