There are many reasons to use Microsoft Edge for the new Bing. Here are some of them: *

You can ask questions and get complete answers side-by-side with your screen without leaving the webpage you’re viewing. You can even click citations from the sidebar and your content will open in a new tab in Edge, while keeping your Chat at the side of your screen.
You can perform searches and answers in relation to the page you’re viewing by toggling on Page context. For example, you can ask me to compare products, summarize documents, or suggest wine pairings for a recipe.
Edge is fast and responsive, and it has features like startup boost and efficiency mode to optimize your browsing speed and battery life.
