This is one of the most requested lenses comparison from my Instagram and YouTube Channel. Since there are a lot of articles out there for technical comparisons, I won't go into all details on the technical aspects. This post will focus on which lens is better for portraits based on my experience.
Colors & Contrast
Below are two original Fujifilm X-T2 JPEG photos taken from the same location. The left is 35mm F2 WR and the right is 35mm F1.4.

Right out of the camera, the 35mm F2 has richer colors than the 35mm F1.4, and the contrast in the 35mm F2 is better straight out of the camera.
Background Bokeh
In the same photoshoot section, here is another example to show the blurred out background for both lenses.
35mm F2 WR on the left vs.35mm F1.4 on the right
As you can see the difference above, the extra stop from 35mm F1.4 does give an edge in terms of blurring out the background. The extra bokeh blur also makes the image feels smoother overall. Overall tone is soften in 35mm F1.4, while 35mm F2 WR gives me a feeling of solidness to me.
For street portraits or environment portraits style, in which style you want to include the location context, 35mm F2 is good for that purpose. It just has enough blur for the feeling, but also includes solid texture from the background. (See 3 examples below)
While 35mm F2 is very good for daylight street, 35mm F1.4 is very good to create dreamy feeling in a photograph. As you have seen in the previous comparison example, 35mm F1.4 has a softer tone than F2 version. I usually use the F1.4 for wide open field portraits. (See examples below)
Price
Considered the price of 200 dollars differences (35mm F2 WR $349 on Amazon vs 35mm F1.4 $549 on Amazon) If I just switch over to Fujifilm and have a limited budget, I would buy the 35mm F2 to start with because it's pretty solid at this price point. Then after getting familiar with Fujifilm system, you can upgrade to other lenses.
If price is not a factor, I would recommend to have the F1.4 version. The extra stop is important to me since I like bokeh so much. In addition, the 1.4 attracts more light under the low light situation. Lots of people asked me "If I can only grab one lens between these two, which one would you choose?" I would say 35mm F1.4.
Summary
In summary, both are very solid lenses. Here are some highlights for each lens:
35mm F2 WR - Richer colors and better contrast right out of the camera; Nice for street context / Environment style portraits.
35mm F1.4 - Softer and dreamier tones; Better bokeh and great for backlit photos.
