I have the 14 and in a word it is a superb must have lens ( I don`t use it as often as I should) I have the 23 f1.4 and it is again a superb lens ( I keep that on one of the cameras most of the time) I have the 35 f1.4 and again it is superb( always in my pocket) I have the 18-55 and to be honest I find it unpredictable, when it is good it is very good but quite often it disappoints ( I`m told to keep the IS turned off but whats the point of that) I never use the 18mm because although it`s not a bad lens it can`t touch the IQ from the 14 or 23 so I move around to frame up. I`ve never used a 56mm lens, I keep my 55-200 on the other body and being a superb lens considering the focal range it does everything I need of it.. so when I go out now days, I have a dual mount harness, XT10 and X-M1 (soon to be XT10+XT20) 23mm on one, 55-200 on the other) domke camera vest with 14,35 or just pockets depending which jacket.
I don`t like changing lenses out and about and the 18-55 would fit the bill but with these newer Fuji cameras it`s all about image quality for me.
So, I wouldn`t be without my 14, 23, 35, and 55-200 that way I know with a bit of moving around I have everything covered.
