I'm eyeing a few right now. I found the iPhone X not a good value for the features. The only reason I'd buy it would be for the ecosystem/integration with other apple products. The 3d facial recognition is awesome though. All phones need this type of unlock tech in the future.
The OnePlus 5T seems to be getting a ton of attention on YouTube by all the tech reviewers and is half the cost with same features.

I'm also looking at the Pixel 2 XL and patiently waiting on the S9 although not expecting anything drastic. Biggest gripe about the Samsung phones is their shitty GUI touchwiz that's slapped on top of Android.
