Rust

* is a lot simpler

* has a package manager

* has type classes (like interfaces with default implementations)

* doesn't have multiple inheritance or inheritance

* much nicer unified error/exception pattern

* amazing compiler error messages

* makes memory corruption and many forms of concurrency errors impossible(outside of ffi and unsafe)

* has tuples+sum types w/destructing

I like cargo and easier threading. The syntax is annoying though. C/C++ really would benefit immensely from a central library repo.
