Me too, but I am using mostly Cubase 6.5, some times N5.5.
Cubase 7/7.5 (owned since release) and Nuendo 6 (trial) are not much in use due to the new Control Room and Mix Console.
As for not having a comparison chart between Cubase and Nuendo, that is just UN-PROFESSIONAL.
I do music only productions, and what I miss the most from Nuendo in Cubase is:
The forth mixer.
The split to mono/join to stereo function.
Some automation options.
The extended routing can be handy.
As for the whole NEK ting… Nah, I won’t go there (finished that discussion, no matter how stupid).
