I switched back from Android to iOS as my everyday mobile OS a few months ago, mostly for stability reasons. I think that both OSs have very mature GUI styles, iOS more visually appealing in theory (smooth animations, Gaussian blur; just compare Chrome's tab switcher with Safari's) but also more conservative. Material design is certainly easier to "get right," meaning that more third-party apps look quite polished than on iOS (it used to be the other way round before Material came up). Before the switch, I thought that I would continue to use iOS versions of Google's great Android apps (especially Keep, which on Android has way better UX than many alternatives). Actually, I more or less abandoned all Google apps except Maps. Material Design is only one reason, but certainly a big one. Once I got used to the iOS style again, those colorful hamburger menus felt out of place. All in all, Google's apps felt like "bad citizens." I don't want to rethink my interactions between apps. What made me angry (obviously that's because I'm a nerd) is the Roboto font, which looks quite similar to San Francisco, but still noticeably different. This violates typographic principles: you don't mix Helvetica and Univers, it will look like an accident. Heck, even Apple Music on Android uses Roboto. Can't you try to be a good citizen in return, Google?
