Same. The Gradle setup it was making was insanely complicated, then the Gradle-free script I forced it to make was very simple. There's no way I would've used Gradle without the LLM either.
All our products and tools around them are built by using Gradle, for more than a decade now. We have no Android and no Kotlin-only projects. I would never switch it for Maven. In fact, I don't remember the last time I used Maven for a Java project. But I guess everyone has their preference.
Maven does not properly do the job for kotlin projects. The Kotlin ecosystem and all of its plugins are very much gradle focused. You have to do bizarre things in maven to get them to behave properly.
