I sent my 35mm f2 back to the shop.
My copy of the 35mm f1.4 is way better performer.
The points for the 35mm f2:
1. Inner fokus
2. Silent. It "sounds" quicker, but I think its only 10% better AF performance
3. A bit more wide. Around 3-5mm than the 35/1.4
4. Weather resistance
The points for the 35mm f1.4:
1. f1.4 - f1.8
2. A little more nice Bokeh on f2
3. From the middle better performance and in the corners the clear winner. Also on f4 the lens is more detailed an crisper.
Please have a look for yourself. All pics with a tripod.

Thanks for posting the sample photos in the link. Much appreciated. Not that it amounts to much in my opinion but I notice, in the two images of the hotel (?) with the flower boxes, that the 35/1.4 shows a bit more distortion than the 35/2 (look at the horizontal line across the top part of the images). And in the two images of the iron fence, assuming you were carefully focusing on the acorn piece in the center, the 35/2 'acorn' is sharper or has more contrast.
