They're both good at different things:

NoScript blocks Javascript/Flash/etc. based either on a list you import, or on a case-by-case basis. I use it as a security measure, blocking potentially harmful content by default and enabling it only if I need it for the site to function.

Privacy Badger is not designed for security so much as it is for protection against non-consensual tracking. It observes which third-parties store high-entropy cookies on your device. If it sees a third-party domain doing so across three different first-party websites, it automatically blocks requests for any content to that third-party from your browser.

So I'd say the big differences are Privacy Badger is set-and-forget, while NoScript isn't; Privacy Badger protects against different tracking (including pixel tags); NoScript protects against some first-party tracking (if you don't allow JS on a first-party domain) and security dangers.

Full disclosure: I work for EFF which makes Privacy Badger.
