I’m also engaged in writing website builders reviews, and I must say that confronting WordPress (which is an open source platform) with Squarespace (which is a ‘pure’ website builder – http://superbwebsitebuilders.com/squarespace-website-builder-review/) can be a tough task.

I think both services are good, but for different pursposes. Those who are handy with code and try to save some cash would prefer WP, while those who prefer taking shortcuts are more likely to choose SS. I’ve confronted these two platforms on my blog: http://superbwebsitebuilders.com/squarespace-vs-wordpress/.
