If you use many services, often with the same company (say multiple Google accounts) it doesn't look that clean; you have many repeating icons. Many of which, you'll get a generic key (if only they'd let me add a custom icon). Then you're stuck with reading that tiny font, which requires several seconds of scanning, even on a 6 Plus.
There seems to be two types of people here who like/dislike it. With few services they love the new design, and with a lot they hate it. The Android app was also updated to the square icons on the bottom, the drawer was much better if you had a lot of services added.
