Rust is actually much closer to unique_ptr than shared_ptr or weak_ptr. The use of Rc is pretty small in practice.

The thing is that even with unique_ptr I can easily reach in via get() and I've broken the shared mutable state contract. It's trivial for me to trace what modifies things in Rust, I just follow the 'mut' annotations and since only one thing can hold it at a time it's very straightforward.

Rust also has one the best package managers I've seen. Union types which are the best way to represent states and state machines bar none. An iterator class that's the best I've seen(seriously has anyone actually used <algorithm>? How man begin/end pairs do I need?).

Plus the community is super-welcoming, there's more reasons but those are my top ones right now.
