Please advice, thanks Adam!
That depends on what your needs are. Elementor Pro has some nice features to it that may make it worth it for you.
For example, some of the modules you may need are, forms module, pricing table, countdown timer, posts grid, and a whole bunch of others.
Also, there are better templates, global elements, shortcode templates, and more features in Elementor Pro.
So it all depends on if you need those.
