Yes!!! I have both, well my wife has the F2, I have the f1.4 and two X100's (an original and an F), I'm a bit of a 23mm junkie..... Basically IQ wise you get what you pay for, if you want ultimate IQ (and F1.4) you get the F1.4, if WR is your priority you get the F2.
The 23mm F1.4 at F2 is as sharp as the X100F at any aperture!! the 23mm F2 is in between. The biggest difference isn't in the middle, it's towards the edges and corners, so if you are just after centre sharpness you might get away with the F2, but the F1.4 really is in a different league.
With regard to the Fuji primes (I've owned most many of them at some point*), IMO the 16mm, 90mm and 23mm F1.4 stand above the others.
(*Not owned 80mm macro, 200mm F2, 50mm F2 and 35mm F2)
