I'm not sure how well "less tools" holds up when Jetbrains has done an awesome job of supporting Kotlin in their Java IDEs. There's something to be said for a dev tool shop developing a language.
To have used both, Kotlin is probably the #2 language with best IDE support, and the gap between the #2 and the others is as huge as the gap between #2 and #1 (Java)!
Java has much more inspections, more intentions and some next generation inlay hints such as the "related problems" view.
Thankfully Kotlin is catching up (and is e.g currently getting support for code vision)
On the other side Kotlin is THE language optimized for developper Happiness/ergonomics and its shows that it has been designed by IDE developers.
