Gives you more flexibility and freedom that most scripting languages. The syntax is clean and concise, the tooling is amazing and can compile to JVM, JS, Native and WASM.
I have used Kotlin a bit for a hobby project and it felt like they were 95% done with a 1.0 version. I love the promise of a single code base that can run on the JVM and browser, but it is not all there. Until recently, the API was not guaranteed to be stable. Every one in a while, I hit a feature that is JVM only or does work right in JavaScript. The JS compiler will "helpfully" remove uncalled public functions unless you explicitly mark them with JsExport.
Also, from what I can tell, only InteliJ is the only supported IDE (which makes sense, since they are the language developers). There is an official Eclipse Plugin, but the last time I tried it, it did not work and tried to take the entire IDE down with it.
Having said that, it was very close to complete and I have not worked on that project for a few months, so it could all be perfect now.
Kotlin jvm is extremely stable, not sure what issues you could be encountering there. The API has been guaranteed to be stable for years and years now. And sure, the other stuff has experimental functions, but they’re clearly marked.
I don't want to use Kotlin on (just) JVM. The reason I am working with Kotlin is Kotlin Multiplatform (so JVM and JavaScript). The JavaScript side is where all of my frustrations have come from.
Kotlin without a doubt.
