I just came from Best Buy and saw it in person....
The Pixel 3 XL's notch isn't "ugly" but it is a huge waste of screen real estate, resources, and effort. Google was obviously just following the trend rather than designing the phone as it should've been. With small notches or the teardrop notches that are becoming common (like the one plus 6t), using full-screen and overlapping content into the notch area isn't that bad since you're not missing much of the content. For example, if you really wanted to, it wouldn't suck too much to watch a youtube video, use the camera app, or play a game in full screen on the OnePlus 6t. But, the XL's notch is so big, that you basically have to keep content out of the notch area of the screen because it'd be blocking too much content. Also, it seems silly to wrap around to the corners of the top of the screen which are too far to reach and touch, but still have a bezel chin at the bottom. On top of the notch not making sense from a usability standpoint, it is asymmetrical, just as the original Pixel had an asymmetrical design (earpiece at the of phone with nothing at the bottom where there should've been stereo speakers). Google should've just made a larger version of the regular sized Pixel 3.
