To date, I have not gone with a premium theme. I’ve always built upon free or open-source selections using a child theme for my customization. There are a few premiums though that I really would consider purchasing, such as Parallax, Divi and one that has recently caught my eye, Vertex.
Not to be confused with the free Vertex by Shape 5, Vertex by Elegant Themes, is ideal for a complete website, blog, portfolio, emagazine, or however you choose to deploy it – this theme has a lot of capability built in. With Parallax scrolling, shortcodes for boxed content, toggled content and tabbed content, slideshow, image slider, column layouts, button varieties, and literally tons of other cool features, Vertex is definitely one of my favorites.
