Thank you for the feedback. It would be nicer if a good reasoning is provided, though.

ScrapBee seems to be a quick implementation of ScrapBook in WebExtension, while WebScrapBook is targeting a complete solution for web scrapbooking, and lots of improvements are implemented, such as cross-browser support, mobile support, remote backend server support, archive file support, more flexible capturing options, more flexible data structure, more portable static site index, and markdown note support, etc. Some features are not yet implemented but are on working. It'd be good to do a further investigation before making a judgement.
