Divi will not be able to support all of the features as you’ve stated out of the box. With integration of things such as WooCommerce which Divi prefers you use, you’ll be able to incorporate features like the quote but probably not on the product comparisons.
That being said, DIVI is a very powerful theme, but keep in mind that many themes will need customization for things like e commerce. You may be able to avoid the comparison with a filter to display multiple products of the same time instead if that’s a suitable work around. You could also look into SHOPIFY if that management system offers you more of what you’re looking for.
