Android for me, currently the Pixel 7.
I've used almost everything at this point. Apple iOS, Android, blackberry (both pre and post android), even Windows Mobile for a while..... I enjoyed Windows Mobile for the time, since it was good for my specific application of the technology, but that was before Android, and during the early days of android.... I stopped using it because they stopped making anything good that ran it.
I moved on to Android with the Motorola Milestone (aka the DROID), but also made my way through several HTC phones as well, eventually landing on pure android with the Nexus line, and eventually Pixel.
During all of this, I hopped through several blackberry phones for work, including pre-android versions, and later worked with several android-based versions of the same, a few years ago I picked up an iPhone to compare and learn more about iOS, because I do tech work and knowing a diversity of things is important for my work; so I carried around an iPhone for many years as well, as a work phone.
After all of that, Android is still my pick. Specifically the unflavored android from Google via the Pixel.
I don't hate iPhone at all, I just don't prefer the stock keyboard, the gesture controls, or the navigation of it compared to android. I still use the three button nav on my Pixel instead of the gesture controls. I also don't like how many controls for apple are at the top of the screen for some reason so I'm constantly stretching my hand to hit a button. It's all personal preference, and the navigation is competent, I just don't like it as much as I like android.
It doesn't hurt that I can customize my android experience more than I could with iPhone. I don't necessarily want every app I've ever installed on my home screen somewhere.
That's just what I prefer.
