I absolutely love mine! Gotta be honest, I was a bit sceptic about some things at first. The color for example: I wanted Silver, but after days of not being able to reserve that one I decided to go for Space Gray. Never disliked the color, but I thought silver looked simply more 'classy'. Good thing I chose Space Gray after all, because I do like the color now. In fact, it looks better on the iPhone X than it does on my iPhone 8 Plus, that I can tell you. And despite the ever bigger screen it feels almost like my old iPhone 7. Yet it has almost everything - plus a lot more - from the iPhone 8 Plus.
OLED: Amazing, with a capital 'A'. I've seen OLED displays before, but actually having a phone with it yourself is different. I watched this YouTube video with 4K HDR and it looked phenomenal! The immersive experience makes it even better. Easily one of the best features of the iPhone X.
Was sceptic of Face ID as well, but it turns out it works great! Yes, there are moments where it doesn't work immediately, but most of the times that's because I hold my iPhone too close to my face. Anyway, what I also like about Face ID (and TrueDepth in general I guess) is how much more convenient autofill for accounts works in Safari now. And the feature where notifications are hidden until you unlock your phone is a nice one too.
Wasn't sure about the gestures either, but I've got used to it pretty quickly. I find myself swiping on other iPhones constantly now.

I think it feels more natural and faster as well, compared to using the home button.
Performance is top-notch, but since I've had the iPhone 8 Plus already no new stuff there. As for the camera: the wide-angle lens is exactly the same, but the telephoto lens has notably improved. And portrait mode with portrait lighting on the front camera works better than expected, as long as there's enough light.
I'm happy with this phone. More than just that in fact. Glad I upgraded from iPhone 8 Plus, even though my initial plan was not to do so and wait it out until the next model. This really is a good phone.
