The Internet and web browsers are an ever changing congruous mass of standards and design. Browser development is a delicate balance between features, security, compatibility and performance. However, although each browser has its own catchy name, some of them share a common web engine. Regardless, if you are in a business environment that's rolling out Windows 10, and the only browsers you have access to are Microsoft Edge or IE — go with Edge. It's the better browser of the two by far (security not withstanding). If you do have a choice, then there might better options to consider, depending on your use case. The performance differences between browsers currently are less significant than one might think. If you exclude IE, most browsers perform within 10-20% of each other, depending on the test. For web standards compliance like HTML5, Blink browsers (Chrome, Opera and Vivaldi) still have the upper-hand, even beating the rather vocal and former web-standards champion, Mozilla. Edge seems to trail all others in this area even though it's often the fastest in various tests.
