If you want a consistant look across all of your primes I would go with Rokinon/Samyang. The 14mm isnt very good but all others are in my opinion. They all come in Cine versions too. I have 16, 24, 35, and 85. Use them with the Nikon Speedbooster.
I know it isn't a prime lens but I would seriously consider getting the Sigma 18-35 with a Speedbooster. I have been using that lens now for pretty much 75% of shooting. It can cover all of your ranges from 14-35 (with speedbooster of course).
