Stable rust is perfectly fine. The vast majority of Rust users are on stable only.

Unless you want to try out Rocket. That one STILL requires nightly...

Rocket 0.5 (which is coming soon) will compile on stable. Alternatively, you can the master git branch directly. Very few libraries still require nightly. Most of them have moved or are moving to stable.
