I haven’t made a move yet on the upgrade but 8+ user here.
FID:
Wife has had FID for a year with her X (which she loves.. upgraded from 6S+) and she loathes FID. For her it works less than half the time. I see her input her code all the time. On the other hand, this weekend I was caught in a rainstorm with my wife at an airport in Dallas (we are in Jax) and I could not answer or access my phone because TID and the screen would not recognize my fingers. I have since setup Hey Siri. I was able to use my Apple Watch to text her. It did make me think. TID is faster IMO.
XSM:
YUUGE.. and king of video. Outside of video, IMO, there isn’t THAT much difference in it versus the 8+ or X for that matter. You get some more text on the screen (more than 8+ and X) but how hard is scrolling. Battery life will be about on-par with 8+ IMO. Apps like Radar Scopea and Sky Guide will be amazing on the XSM. However, in basic non-video use.. the gap between the XSM and 8+ isnt’ that wide.
If you are into photography...
The new iPhones have an amazing camera but so does the 8+ and iOS 12 has brought improvements, even if not adverstised, IMO. When it comes to photo editing on a phone (maybe not many people do this.. I do it a LOT) the 8+ is KING. Go to an Apple store, pull up a landscape image on the XS, XSM and an 8+ and look how much more workable are of an image you get. I was very surprised. I personally load a lot of images from my real cameras onto my phone for editing.
Basically, I am on the backside of this issue. When I look at the XS and XSM I wonder if it is worth the upgrade from my 8+. From everything I have ‘analyzed’ the XSM isn’t worth it, for me. I lose photo edting space and gain screen for a few apps and videos that I don’t watch that much. The XS on the other hand gets me to a smaller profile, which I have been wanting but costs me photo editing space/size. In the end, do I want a smaller profile phone and would I be OK moving my photo editing to my IPP.
I have to admit that there is a part of me that wants to get the XSM just because it’s so honkin’ big and that screen.. that glorious big@$$ screen. It’s tempting for sure. My pinkie, however, is on my other shoulder saying nah.
