Maybe I'm still in the honeymoon phase with my iPhone X, but I've had it for a few months now. The last iPhone I owned was a 4S, and I've been on Android ever since. I was very happy with Samsung's Galaxy line from the S4 Active to the S7 Edge, but the Edge simultaneously slowed to a crawl and lost at least half its battery life after 18 months. It was to the point that I had to charge it every time I was sitting down.
The iPhone X has been great. The interface is fast and gets out of the way, and Siri is actually starting to become useful for more than a parlor trick.
FWIW, I'm writing this from a bluffline overlooking a lake. My MBP is tethered to my iPhone, and I'm getting a consistent 50Mbps. I don't know that additional download speed would be useful to me at the moment.
