The 35/2 creates images with greater contrast. This will look sharper, at least to some. When the image has greater contrast, you can make it look less contrasty, but you cannot gain back the smooth gradation which was available.
The 35/1.4 creates a smoother image. It is easy to add contrast in post or using the JPEG setting in the camera if you want the images that way. With the 35/1.4 you can have it either way.
The 35/2 is significantly corrected in the Fuji JPEG converter and in LR. You do not have the option to turn it off in LR or Fuji, although you can in other RAW converters. The 35/2 is softer away from the center. There will be softness and/or image degradation at the edges.
Fuji made image quality the top priority for the 35/1.4. They went so far as to have multiple moving elements to focus the lens to allow for better image quality. This is why there is a limit to focusing ability, although it has been substantially improved and is now quite good, it isn't as fast as the 35/2 lens in good light and cannot be made so. In low light, the 35/1.4 focuses better because it is a faster lens.
The 35/1.4 is far sharper at f1.4 than the 35/2 is .
Pick what you like better, be happy and make images. Both lenses are good lenses. There are reasons to prefer either one.
