I was a long time Android user when they were still releasing the Samsung Note phones because I wanted a nice big screen and the customization of the format. Switched to a Galaxy later on. I still keep some Android stuff alone for niche things today because I like tech stuff, but they are not my daily drivers.
What keeps me on iOS, MacOS devices is the fact like others have said, they all play very nice together. I can access my Pages documents, Numbers sheets, Apple Music, calendar items, photos, all from my various devices and they all load without any complications. Plus having Airdrop is a godsend. I don't need to plug anything in, and I've had it fail to work a couple of times, but that's two times, out of hundreds I've sent or had things sent to me. Pretty rock solid, everything just works. I didn't realize what it was like until I switched. Don't plan on switching back as I trust Apple with security and data more than Windows and Android at this point and time.
