I'm a long time nexus/pixel user also considering switching to iPhone. For me, it's more about wanting a good integrated smart watch, and the pixel watch seems overpriced and has a weird half-baked FitBit integration in typical Google style, and I don't want a Samsung watch or generic fitness tracker.

One thing that's been holding me back, though, is notification management. I love the little app icons at the top and the pull down shade and such. I don't have that much experience with iOS, but it seems notifications work fairly differently. Has that been an issue for you?
