I initially found it much harder to work with Rust, as the language is more strict in a number of ways. But once I began to understand how it works, and began to grasp some of its concepts such as ownership and lifetimes I found it much more powerful than Go.

Go has a larger community right now, many more libraries and resources openly available. That's probably one of Rust's downsides right now however its catching up, especially with the launch of crates.io. I don't think it will be long in maturing following the 1.0 release.

Saying that, both are enjoyable to work with. But for me Rust wins out!
