What are the real advantages of Kotlin, which emerged as an alternative to Java, in the Android development process? What differences does it offer in terms of learning curve, performance, or developer experience? Which one is more logical to choose? I would be very happy if you could share your experiences on the topic.

I also started with Java, coding in Android Studio for months within a project team. After a while, I switched to Kotlin, and the biggest difference was the reduction in headaches caused by null safety issues. Once, I forgot to add null checks for a method in Java and got a crash, but in Kotlin, the compiler catches it immediately and forces me to fix the code.
Another thing was data classes. Before, I had to write a lot of boilerplate code for model classes, but now I can just write `data class User(val name: String, val age: Int)`. It's easy to learn, and its performance is as good as Java's. That's why I prefer Kotlin directly for new projects.
