I'm sure it can be the better choice, but for me it was not.
It seems there was some incompatibility between me and Scala. I find it such a complex language and I never managed to wrap my head around it.
As I said F# was my last choice at the start of my evaluation, and Scala was high on the list due to the Java ecosystem. But in the end it didn't work out for me.
F# on the JVM would be great though!
