Use Kotlin Dispatcher as Executor, or use Java Executor as Dispatcher?

Kotlin provides its Dispatcher interface for the purpose of dispatching coroutines, and default implementations in Dispatchers.Default and Dispatchers.IO, and you can use one as a Java Executor with .asExecutor().

Java also provides its own implementation of Executor in the form of ForkJoinPool.commonPool() which I can use as a Dispatcher with .asDispatcher().

So I can either use Kotlin’s default Dispatchers as Executors, or I can use Java’s default Executor as a Dispatcher.

Which one should I pick? I can’t seem to find any information on the pros and cons either way.
