I've been using WordPress to create client websites but recently looking for a simpler, more integrated solution. SiteJet really met this requirement with a platform facilitating the design, requirements gathering, site-building/SEO and tracking of additional content or changes once the site is live.
The WYSIWYG drag and drop site builder itself is very intuitive and easy to use, with handy live guidance provided. The site can be previewed at any time during the design process, including all of its responsive views (for mobile, tablet, desktop etc) which is incredibly useful.
There are also plenty of templates and 3rd party integrations to get started with which has definitely increased my productivity. Review collected by and hosted on G2.com.
