A fundamental difference between what Orion is having and NoScript is ability to select which script from the website to be disabled. The premise of NoScript is for letting users to preemptively choose and block malicious scripts/trackers by their own.
For example, when visiting CNN.com via a browser with NoScript, it is possible to enable javascript originated from CNN.com while disabling third-party trackers embed in CNN.com (e.g. doubleclick.net, chartbeat.com, etc.). In contrasts, Orion (in iOS) disable all javascripts embed in CNN.com (functional javascripts, trackers and everything in between). Without a choice to select, and all javascripts are disabled, this breaks many websites to the point of unusable/unreadable (especially the ones with JQuery).
To my knowledge, there is no mobile browser capable to do this natively. The closest example would be Kiwi Browser on Android, which supports NoScript extension.
