I have sold all my NX1 gear. I love new things, but to be honest; NX1 has a way better grip and I liked that camera a lot. I hacked my NX1 and that improved quality, but the dynamic range had also his limitations, especially on skintones at sunny days (whitening out). I use my camera mostly for filming with vintage and anamorphic lenses. Sometimes I use the camera professional photos for a magazine. X-T4 has a bigger battery and IBIS. Also the smart switch between photo and film is a big plus. I think when X-H2 comes out, I switch again, but then I will keep my X-T4 for photographing.
