Designing for Squarespace is by far the simplest process I've used. It's way ahead of even Shopify, which has been touted as being incredibly easy to design for. I can take 90-95% of a completed PSD design to Squarespace in under an hour. If the design is already chopped up in HTML, even faster. It cut my site development time in half, and my clients prefer the user interface versus Wordpress.
The "Selective Display" section are comparable to Drupal, yet they are much easier to work with.
My frustration with Squarespace's previous version (Version 5) was that it was getting a bit dated and it was a bit closed off, meaning some designs and project were just not possible. Squarespace 6 is solving a lot of this.
Regardless of whether or not it's a threat to WP or Weebly, it's an awesome platform to work with and has many features that are simply amazing.
