Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I had a great experience with Scala and hopefully it will get more popular
So does Java! Also, kotlinx.collections is still not stable and I don't think they are intending to make it so any time soon.

what is the best persistent collection library?
kotlinx.collections.immutable it's a kotlin-focused collections library, but it can absolutely work with Java, especially because it extends the standard collection interfaces, so you can simply get an iterator from it
What I know is only based on this discussion. It seems that pcollections is really outdated and should not be considered.

A personal Kotlin guide for Java developers
If you want true immutable collections, kotlinx.collections.immutable provides them. They will likely be integrated into the language eventually with value classes and better immutability support.

Scala is a Maintenance Nightmare
I could see this argument made with Clojure, but I don't really see what makes Scala significantly better at FP than Kotlin. Kotlin has an official persistent data structures library nowadays, and it's got lambdas and higher order functions.

What are your concerns and pet peeves about Kotlin so far?
It's not immutable, it's read-only, https://kotlinlang.org/docs/reference/collections-overview.html . I think that's a false assumption. But I get the point - immutable collections are not part of the std - for very good reasons. But we know each other, I assume that you will disagree :) For people who know what they want and know all the implications, there is https://github.com/Kotlin/kotlinx.collections.immutable .

what is the best persistent collection library?
I'm not sure which one is best, but I always wanted to give https://github.com/brianburton/java-immutable-collections and/or https://github.com/lacuna/bifurcan (which, strictly speaking, does not satisfy your requirements, read the description).
