ThemeHybrid is free, but to get support on its forums, you need to sign up for an Exclusive Membership to their Theme Club, which is $25 per year.
ThemeHybrid has many child themes available for download on its website, which you can use to give your WordPress installation a new look without much coding. ThemeHybrid comes with plenty of WordPress widgets and page templates. While many people say that frameworks are bloated and slow, ThemeHybrid will change their mind as it is lightning fast and optimized for high performance.

You can style each element of Canvas differently from its Theme Options panel.

Canvas also supports 6 CSS layouts for your blog and even provides you an option for choosing distinctive layouts for each post and page.
Genesis is a premium theme framework that was built by StudioPress. Genesis has a child theme marketplace where you can buy all additional child themes.
Genesis has native support for search engine optimization (which it focuses on). You can set all the options in the Genesis backend panel, just like with most good WordPress theme frameworks. Genesis gives you the option to select separate layouts for each post and page. Genesis is intended for developers, as opposed to designers, because you will have to learn its hooks and filters before getting started with it, and thus, will need some coding proficiency.
Elemental is a product of ProThemeDesign.
One of its unique features is that it comes bundled with an admin menu bar that stays on top of your WordPress web pages if you are logged in. The admin menu bar allows you to go to the most common places inside the WordPress admin dashboard. The framework comes with 12 page templates and 7 custom widgets by default.
