My Personal Findings
There is a difference.
X-E1 has more “punchy” colours
X-E1 has more contrast
X-E3 is better at reflecting what the real scene looked like
So.. how did I get there ?
Background
There have been countless number of content creators/photog community members praising the image output from the X-Trans 1 (X-Pro1/X-E1…).
Some may say there is a “cult” following for cameras with the X-Trans 1 sensor, these are sought after on the used market (eBay) as they have been more difficult to find used in mint condition.
So when an opportunity to purchase a “near mint” X-E1 (kit) – I didn’t hesitate and pulled the trigger, as it would be a great opportunity to form my own opinion, and share / contribute my findings with the "innerwebs".
Purpose
Compare out of camera RAW image for a few “Real world” scenes (I did take FINE JPEG as well), I wanted to see if there was a difference compared to my X-E3 (X-Trans3) OR if this was all made up.
What's been frustrating is individuals sharing amazing photos taken with X-Pro 1/ X-E1 .. during their ownership. Touting it's "unique" properties of X-Trans 1 had somehow added some additional magic property to their photos to make it even more amazing. However the argument could be made that the same scene could be reproduced with any camera, by the same photographer.... basically...I was missing a direct real world comparison for a given scene.
Raw files + out of camera JPEG will be provided, so you can use your tool of choice if you would like to perform further analysis.
Additional Clarification on "Compare camera raw image"
“Compare camera raw image” = What I find more pleasing between the two images from a colour perspective prior to moving any sliders in your editor of choice.
Controls
-Base ISO used on both cameras
-X-Trans1 (X-E1 + 18-55mm)
-X-Trans3 (X-E3 + 18-55mm)
-I will be shooting Raw + Film simulation (Provia) on both cameras
-Film simulation will not be tweaked (all zeros)
-DR100 for both cameras
-Same exposure will be taken on both cameras for a scene
-Same lens model (18-55mm)
-I’ll try to find meaningful test scenes that I find interesting (i.e., no brick walls)
Caveats/Constraints/Limitations
Understand the following parameters will influence the output, however due to my limited time, I won’t be able to address the following:
-No control lighting, no props (Scenes will be outdoors)
-White balance – Both cameras will be set the same WB profile (i.e., DAYLIGHT, CLOUDY etc)
-There is more to a camera than output – but I won’t be testing/commenting on DR/NR/AF/AWB/handling etc
-Test scenes is only limited to my place of residence (5 minute walk)
-No baseline image - Capturing the "true to life" colour representation of a scene
Errors identified during my process of creating these test photos
1. White balance “preset” have a different value between the two cameras
X-E1 – Sunny is temp: 4900 tint: 13
X-E3 – Sunny is temp: 5000 tint: 12
2. Between images the framing may not have an exact framing (e.g., zoom 37.4mm vs 36.3mm)
3. I didn’t use the same physical lens (same model i.e., 18-55 2.8-4, but not the same physical lens), this was done for convenience, as changing lenses between the bodies would just be too cumbersome.
Acknowledgement
Lots of threads and content exist on this already, however I didn't find one that compares X-Trans 1 vs X-Trans 3 (directly)

Raw / OOC JPEGs?
Yes, for the purposes of construct a supporting / alternative view – View here
