World of WordPress uses GeneratePress
We switched to GeneratePress last november. Because OceanWP, very good theme by the way, didn't offer us what we needed. Plus we wanted to stop with Elementor.
GeneratePress comes with lots of options. If you want more, you can buy GeneratePress Premium. We wanted more, so we bought it! Although there is still some work to do, the new theme, together with the views of Toolset, works out great for us!
