Which of the many Spark/Scala kernels for Jupyter/IPython to choose? [closed]

I can’t speak for all of them, but I use Spark Kernel and it works very well for using both Scala and Spark.

I found IScala and Jupyter Scala less stable and less polished. Jupyter Scala always prints every variable value after I execute a cell; I don’t want to see this 99% of the time.

Spark Kernel is my favourite. Both for Spark and plain old Scala.
