No external widgets in DIVI page builder:
You can’t install a widget plugin and import it to a webpage using the DIVI page builder. On the other hand, you can’t install a widget plugin and install it on a page using elementor.
DIVI 3.0 is fast
I have found that DIVI 3.0 was faster than elementor. When I saved my work, it is always faster with DIVI than with elementor. I think that DIVI is one of the fastest wordpress page builder on the market.
DIVI 3.0 is stable
One Elementor has been unable to load on a website and it appeared it was because of Cloudflare.com. I have never faced any problems with DIVI 3.0
Elementor is easier to install
A free version of Elementor can be installed from the wordpress plugin repository. On the other hand, the DIVI 3.0 page builder is only accessible from elegantthemes.com.
