I have both the Oly Pen-F and the Fuji X100V and I wouldn't sell either. Both cameras are great in their own way. In fact, following my purchase of the Fuji X100V, I learned to appreciate my Pen-F yet more. The Pen-F feels as good, and perhaps better, than the X100V in the hand. The Pen-F has image stabilization while the X100V doesn't. The Pen-F takes interchangeable lenses while the X100V doesn't.
Back in the old film days, at times, I carried two identical cameras, one with color film, the other with Black and White film. These days, I (once in a while) carry two cameras (the Pen-F and the X100V), the Pen-F with a 50mm (equivalent) lens aboard, the X100V having a 35mm (equivalent) fixed focal length lens of course. Both cameras together are small and light enough to fit in a small camera bag.
Just maybe, later on, you'll decide to sell the Pen-F (or the X100V). But why hurry to do so? Take your time; shoot with both cameras for a while. Perhaps a year from now you'll decide to sell one or the other. And perhaps you won't. In the meantime, you'll have two great cameras to use.
Hope this helps,
Bill B.
