Apple

I've had several models of both Android and iPhone over the years. I just like iPhone better. The ecosystem just works well. Apps are relatively consistent and reliable. The UI is smooth. And my iPhones have consistently held up longer over the years. My current phone is almost 5 years old and it works as well as the day I bought it. Every Android I've had is left behind after just a couple years. They would get bogged down with junk files and constant crashes.
