I am not exactly sure what you mean by services. I have used some of those cheaper options and most are junk. It really comes down to value, and what is valuable to the individual buying the device (or anything really). For me, I value performance, build quality, security, privacy, ecosystem, and support. There isn't a phone out there that can beat Apple when it comes to those things. It's a similar comparison to a car. Sure, you can buy a Kia and get from point A to point B, listen to music, bluetooth, backup cameras, all the same "services" as you say, but some people prefer a BMW for the overall experience that that car brings. This is similar to what you are describing and it's up to the individual to make that decision.
