I am big on Rust, and I enjoyed using Scala at work in the past. Scala has a more elaborated type system, and everything is heap-allocated so some stuff is easier. On the other hand... JVM is often a PITA, and debugging blowing up memory issues was common. Compilation was slow (even slower than Rust), code was sometimes slow, and emphasis on OOP has made a lot of code I had to work with overly complicated and very much a typical OOP spaghetti garbage. Null pointers are still a problem (though much less than Java). Compiler is not as helpful as rustc one, though IntelliJ integration was more mature. Lack of macros encouraged code generation which was a PITA. Collections were messed up. Tooling wasn't half as nice.

The list of complains grew big, but again: all in all, I think Scala was quite fine to work with.
