Divi Booster is a good option to get that added functionality without having to code. Divi Switch is another really good, and comparable option. Hard to say one is better than the other. In fact, you can run both at the same time. It comes down to evaluating your needs vs their features. But ultimately, both are solid choices.
Divi Theme is perhaps one of the simplest WordPress themes out there with a lot of features. Divi Booster is an exceptional plugin.
You can use Divi Booster as it adds 50 new configurations to your Divi theme. This includes customizations for your headers, footers, menu, sidebars, posts, pages, and more.
Conclusion- There's no platform deemed to be 'Best' choose what suits you.
