>>7What is bad about the UI? It's snappy, beautiful, works like the rest of the OS and has no unrequired bloat.
What aspect isn't integrated well? What do you mean with privacy concerns?
What do you mean with slow? In usage I have found it to be the fastest observing speed of websites, shortcuts, finding functions (switching tabs, incognito mode, history, exporting), multitasking with the OS (native video player, dropping in and out of apps), startup speed and the home page, which list all favorites space-efficient and without bloat, advertisements or a redundant search bar.
