I have the 35 1.4 Canon L too and also have the 35 1.2 CV and 35 summicron asph and 35 biogon. In the 80's I had a Rollei 3003 system with all Zeiss glass. My 34 1.4 Distagon was about the same size as my 35 Canon L.
As to performance, the Zeiss Biogon wipes out all the others including the Canon which is the closest thing in performance to the Biogon. The CV is quite good for a super fast lens and has flare well under controll. It actually flares less than the 35 asph summicron which is the least of the lenses in flare controll. The 35 Biogon and Summicron asph are about equal in sharpness with a slight edge going to the Biogon at full aperture but the Biogon is a much smoother lens in tonality. The Summicron asph is a bit harsh with flare problems from sources outside the frame. The result in flare in the Summicron is a haze of flare over the subject. The 35 1.4 Distagon just wasn't great wide open and good stopped down. It was just an average lens at best. Going back to the Summicron asph, I recently sold my v4 summicron and since have concluded it renders a much prettier image than the asph summicron but it wasn't nearly as sharp as the asph.
If f2 will fill the bill then the Biogon is the best performer in every respect.
