After owning a Fujifilm X-E2 for 6 years and loving it, the successor would have to be a Fujifilm. I guess I'm still in love with physical exposure dials and the photos that come out of Fujifilm cameras.
The X-T4 is a beast, it's good at (almost) everything. The only downside might be its size and weight, not full frame DSLR kind of size and weight, but clearly noticeable for someone who came from a nimble X-E2. My perfect camera would be a X-T4 inside a X-E body (no, that's not a X-E4).
