There's a big difference between a template theme and a framework theme and this must be understood in order to truly appreciate what Pro can do for you.
A template theme is one of those out-of-the-box theme's that you install on WordPress. They give the illusion of customizability but really you are just working within their prebuilt structure. This is great if you are simply a small business looking for near-zero work / expense and honestly, you'd probably be better off with Wix or Squarespace at that point.
A framework theme, like Pro, is really the future of WordPress. It is a blank canvas framework that provides you with the tools to truly design, build and customize your site from the ground up. The builder is intuitive, the options are endless and you even have the ability to tweak with custom css, or js if you're comfortable with that.
They are also constantly working to improve the platform, add community requested features and speed things up. Review collected by and hosted on G2.com.
As with any platform that attempts to provide limitless customizability, there are bugs or issues that you may run into (though for me these have been few and far between). That said, their support is out of this world stellar and they typically will address issues within the next point release.
That said, they've had a glaring issue with accordions previewing incorrectly (which have been pointed out in their forums starting in 2.3.5 and still existing in 2.4.1). They have acknowledged and replicated the issue on their end yet have not addressed it (as of writing). But, I'm confident that their team will address it and it doesn't change the fact that this is a phenomenal tool.
Keep in mind, even Apple is constantly updating your iPhone's software to squash edge-case bugs. No company is immune to this. Review collected by and hosted on G2.com.
I like how easy they are to use and access all the information you need to utilize your theme. They make it very easy to implement. I think that the prices are competitive for all the benefits you get. Review collected by and hosted on G2.com.
I think that it is great, however, I think that it could utilize a little more user-friendly features. I would love to see them e-mail information regarding your themes rather than make you log in to get it before validating it on the website platform. Review collected by and hosted on G2.com.
