This is a really good comparison between Divi and Elementor from CollectiveRay. The author clearly has been developing sites in WordPress for a long time, and has a lot of experience using both themes. Ultimately they conclude that the functionality offered by the two plugins is very similar, and the decision on whether to buy boils down to pricing - if you're an agency with a lot of sites, go for Divi, if you're just using it on one site or need a free builder, then Elementor is the way to go.
