Clearly, having a slow-loading site will have an impact on the experiences of customers; likely leading them to click away and go elsewhere – directly impacting the site's conversion rates and pushing them towards competitors as a result.
The improved structure of Magento 2 allows it to perform 'full-page caching'; the ability to render pages in full-size for viewers, quickly. Not only will possessing such an ability improve customer experience, but having quicker load times will also be great for marketing techniques, such as Search Engine Optimisation (SEO) too – keeping the website high in a search engine's results page.
Improved Admin Interface
Whilst Magento 1.9 offers a number of tools for website owners to customise their sites,the admin interface used to put in place changes has received much negative feedback over the years. The platform is not built for mobile design and contains a layout that can be somewhat confusing for first-time users.
These issues are solved by Magento 2, as it has introduced a far more responsive and easy-to-navigate layout that will get the user to where they want to go to, faster and without over whelming them with too much information and options.
Furthermore, the interface used for the product page(s) will be far easier to work with, as users will not be forced to click on a number of tabs to get their product created. Unlike Magento 1, the user can also easily add images and video to product pages; video URLs from sites such as YouTube and Vimeo can be inserted with ease, as this is a feature that is default with Magento 2.
