Thinking that Node is somehow more "stable" means you've fallen for Joyent's marketing tendrils.
When Joyent or other enterprisey Node users mean "stable" they mean it in the same sense as Windows XP is "stable". It means you have a bunch of dependencies designed to work with a specific version, and you don't want to do the work of migrating because you have bigger cheques to cash. Stable doesn't mean less features, less bugs, or a slower release pace. Those things just fall out as consequences.
This is also the essence of why io.js happened in the first place. The intened audiences are completely different.
That's probably true... with developers starting to favor things like docker and micro services, along with CI/CD flows all the way to production, it comes down to being very easy to create, test and deploy your services against new libraries, or even replace them with better performing versions as needed.
