I switched my site from the Salient theme to Avada this month and am very pleased with how easy it is to work with.  Avada is by far the most versatile and powerful theme I’ve used.  The support has been great whenever I run into a question.  They seem to have thought of everything with a number of slider options, sidebar menu options, built-in updating functionality, search function with the theme options panel, FAQ and Portfolio are standard, very flexible menu structure, finely tuned font editing,… you name it, they’ve got it.  For good reason, this is the best-selling theme at ThemeForest.com.  I’d highly recommend it for almost any style of site.
