If you mean that the syntax is different, yes, I get that.

CasperJS can also scrape dynamic websites. What criteria would someone want to use ScraperJS instead of CasperJS for that task? Are there features in ScraperJS that don't exist in CasperJS? Does it take 10x less lines-of-code to accomplish the same task? Etc.

For web scraping purposes ScraperJS and ScraperJS would probably use the same lines of code, however ScraperJS has most of the tools you need for web scraping, something that CasperJS lacks (that's not their main goal). ScraperJS is move flexible than just CasperJS. If you want static content just use the static scraper and get lightening fast results. TL;DR: CasperJS is great but it's not made for web scraping.
