After being a big fan of Scala about 10 years ago, I think that Kotlin is better suited in almost all cases. Kotlin is much easier to learn (especially if you know a similar language like Java, C# or TypeScript), much easier to read and understand and has much better long term stability. The support in IntelliJ is also better. Scala causes performance issues from time to time in IntelliJ and there are some language constructs that the IDE doesn't really understand in all cases. JetBrains build Kotlin as a programming language for industrial projects - and it shows.
