Thats a very personal question that only you can answer. The Fuji XS1 is a small sensor bridge camera with a amssive zoom where as the other 2 are large sensor cameras, multiple lenses and by comparison almost no zoom but with far superior image quality.
If you feel like you need lots of zoom a lot of the time you wont see any benefit but if dont need the zoom, want better image quality (particulalrly in low light) and like the idea of having multiple lenses then take a look.
