Google Chrome is still king, but...
So what did we learn? Well, Google Chrome is faster than Microsoft Edge, but...only if you don't have any extras like extensions installed. When you add those in, Chrome slows down to a crawl.
Edge is no slouch, though. It's a very capable browser and after testing it out, I really like it a lot. If Internet Explorer left a bad taste in your mouth, you'll be happy to hear that Edge is a complete reset in the best way possible.
Extensions are coming to Edge and that could — and almost certainly will — slow its performance down, but right now it's nothing but a great start for Windows 10.
