Around 4-5 years ago, Android phone manufacturers started locking down their phones more while not letting them be rooted. They didn't solve the problem of having undeleteable apps waste my time & space with clear advertising plays.
After my experience with the Galaxy S5, I quickly jumped to the iPhone 6 when it came out, and haven't looked back. I've used Android for a period of time in parallel with a second phone, but it only confirmed my reasoning for bailing for the iPhone - the Android experience is just way behind.
