Smridevan -- You may well find your 24-70 is an exceptional lens (many report the same about that being one of Nikon's best), and blasphemous as it might be to say, it could satisfy you and your type of shooting better than the 34/1.4. But of course it isn't 1.4, and it doesn't have the Zeiss subtle signature style of rendering.
But your eyes may not be playing you false.
I'm still a fan of many Canon lenses, sometimes equal to, or even preferred to my Zeiss glass. Then again, I have some Zeiss that is unmatched by any brands I've tried so far. No one focal length or brand will be able to do it all for ever shooting situation, or at a reasonable price point.
There are some bargain lenses out there that produce amazing images, but usually there is a trade off in ease of use or speed of aperture, and certainly build quality differs from more expensive lenses.
With more use and testing, I'm sure you'll understand the 35/1.4 and its particular qualities (I'm not a vested interest -- don't own one, only have the ZE 35/2), and then you can decide if it is your cup of tea or not, and in what situations you will find it most useful.
Now that you've brought the issue up, I'm looking forward to seeing some comparisons between the two lenses.
