I had an x-t1 and kit lens, loved it, really loved it, lens and sensor both amazing. Didn't get an x-pro1 as it was a tiny bit older and has a couple of less features. Sold the x-t1 to get a x100t as I wanted the sensor with what should be a better lens on the x100 v the kit lens on the x-t1. Hated it. The main hate was the autofocus on the x100t, if you don't need fast autofocus and like 35mm view then that is the one to get. I've now got a x-e2. Great balance of size, price, same sensor, can swap lenses.
If you are going to get just a 23mm lens on the two interchangeable bodies then I would just get the x100t. Amazing camera.
