My wife learned photography using my XH1. Until then it was only a snapshot or two on the iPhone. Here second year she earned the "outstanding photographer of the year" award from the Tampa Camera camera club. I've helped her along the way but talked her into getting involved with the Tampa Camera club and a smaller local one so she can hear from other people also.
I recently got her the XH2 and while a camera does not make the photographer - better tools provide more options. I gave it to her and she stated, "you do not touch this camera, I want to learn it from scratch and set it up for myself." She did starting with fully manual and worked from there. The XH2 is a much more capable camera than the XH1. The AF is worlds ahead. She has found the electronic shutter to be quite nice. I have not noticed any issues related to rolling shutter even when she aims the camera at one of the many bluebird and woodpecker houses I have put up around the house. While the XH1 could be a bit "fiddly" - the XH2 is rock solid.
As far as UI - she didn't have enough experience with the XH1 UI to be biased. As she learns the XH2 and how she wants to work with it - she is evolving her programming of the settings to get the most out of it. We often discuss initial setting for a the programs. She much prefers the XH2 UI since the settings can be pre set and tweaked from there. She does not need to check a number of buttons and dials. To her that has been liberating. Now if a couple of bluebirds land on one of the boxes - she can grab the camera, pot on the 50-140 with the 1.4 TC and a simple twist of the program know - is ready to rock and roll no matter the initial settings on the camera. She really likes that.
Granted UI is a matter of personal preference and we humans tend to like what we are used to, but for a general purpose do all camera like the XH2 I think the PSAM is the appropriate UI. For a "slower" camera like the XT5 - there probably is little advantage to the PSAM dial. For example on a Leica M - a PSAM UI would be ridiculous, but on the XH2/XH2s the preferred UI.
Just our experience here in Lake Wobegon where all the men are strong, all the women are beautiful and all the kids are above average.
