At the moment, memory. But a better story looks like in the near future.

Yeah Rust and Go (and D) all have: decent standard libraries (Go exceeds the other two, somewhat resembling Python), a package manager of sorts (Go needsa improve in this aspect, but the strong standard library makes up for it for now, and they are working on it atm), and they're all usually stable.
I think the biggest game changers for any new language is a highly competitive standard library out of the box: web server of sorts that can somewhat scale out of the box is usually a must, but at least a simple enough one is ok too, file IO, crypto, etc are also useful, the less code I have to write the more productive I feel.
Package management is a must too, even if primitive at first (Go's approach is clean and decentralized to some degree, I love that).
