I have no issue with you passing on the X, along with your reasoning, but the way you speak to it does come off as passive aggressive or trying to belittle the person your're comment is directed to. By saying things like "enjoy your beta X phones", you just kind of come off as a jerk. For some people, the X looks great and they look forward to Face ID and the other features. Totally cool for you to choose the 8, there's just no reason to knock others for their choice. There is no wrong choice here since it's a personal preference.
