Scala is one of the best languages out there if your job is to write code. If you spend a non-trivial amount of time reading it, it depends on which of the sublanguages the original writers used.
If Scala is used as "ML with OO features when really needed but not otherwise" it's quite nice, but I would not advise using Scala without a style guide for a multi-developer project.
