Using iPhone X from last Sunday. And i must say it's a worthy upgrade. You get new experience.
I really didn't like the "Notch" of iPhone X when Apple launched it. But to be honest, it doesn't bother me anymore.
Battery is not so good especially if you were iPhone Plus user. Though it's better than iPhone 7/8 battery.
If you are iPhone user, you must go for iPhone X. You won't regret.
