Just got it in the mail a few hours ago, so it's early.
Is this a totally needed upgrade? No, the last phone was, and is, still awesome.
For instance, I took this pano with the iPhone XS Max a couple week ago in Kauai:

That's insane for a phone!!
I really only upgraded because I like having the latest and best cameras.
Also, maybe I just shoot too much 4K 60 video, but I really hammer the XS Max battery and end up having to charge it with a battery backup when I'm out on shoots. So the bigger battery on 11 Pro Max is a welcome improvement.
So far, Face ID does seem faster, but
- It doesn't seem to be better at more angles in my experience. I was hoping to be able to unlock it while flat on my desk. Not even close. Seems exactly the same to me.
- This is the first time I'm using iOS 13 (on the 11 Pro), and I hear that iOS 13 already brings speed improvements to Face ID, so I'm not really sure how different it is.
I will say to my eyes, the screen is noticeably brighter AND more vivid (greens, oranges) on the 11 Pro than the XS, which I like a lot.
That's about all I can say a few hours in at this point.
