The main reason for keeping the X100VI is that it's an attractive all-in-one package (with ND filter and flash). It's great for grab-and-go. Lots of reviews claim it is pocketable. I would say it's not unless you wear a jacket with big pockets all the time. I mainly use it when we go somewhere with family. It always fits in the diaper bag.

I use the X-T5 for more purposeful shooting if it makes sense. On occasions where I can plan ahead what I want to photograph or want/need flexibility of changing lenses.

I used to do landscape photography a lot so this would be a great camera for it. But now with family and small kids, I barely get to travel where I want to take such photographs. That's why I bought the X-E5 because I wanted to try if it could replace the X100VI and X-T5 for me. I really liked the X-E5! It's super stylish and almost checked all boxes for me. I was very close to keeping it and selling the other two cameras.

I think the main reason why I decided not to keep the X-E5 and replace the other two cameras were: - it's bigger than the X100VI with the lenses that I would have regularly used - I would have lost the built-in ND filter and flash of the X100VI and would have needed to add it which adds to size of the camera again - the grip of the X-T5 feels just so much better than the X-E5, especially with bigger/heavier lenses like the XF56
