It’s a matter of taste but I prefer the Apple/google clean and white UI with little else distraction than what you are trying to achieve over Microsoft’s “portal from the 90’s/let’s fill every bit of space”. Whether it’s bing or Windows, something as stupid as showing you a different background picture every time means you always have to deal with a new visual, which means more effort to find your way. It’s the same for IE and edge, the default new tab is to show you a busy page with news, weather forecast, most visited stuff. That’s like advertising banners to me.
