The problem with thinking this way is that you don't know what security issues that nobody knows about yet are lurking in there. I remember the time before the recent spate of Rails vulnerabilities in the last 5 years or so, and I thought similarly about its security as you seem to about the Nodejs ecosystem. It's definitely possible that your confidence won't ever be punctured by a similar run of security issues, but my personal view is that it tends to be hubris to think your favorite technology is just better at security, for vague reasons.
