Design is almost always subjective but amongst the four, NB would come last anytime I rank them 
Feel free to share opinions krub
On NB (particularly Mk 2.5), the overall look seems to be wide and low. It has very subtle curves. The lines of the NB are reminiscent of some beautiful cars of the past ... the XKE and early vettes. The flat rounded rear quarter sections that remind me of the XK-E. It looks light, agile and quick. The biggest selling part is its coke bottle styling which was relatively prevalent during MADMEN/mid-century era. The dashboard console reminds me a bit of those found in Mercedes R107 Panzerwagen (1971-1989). Its 1960s-70s retro design elements really caught my attention when it was debuted in Thailand back in '01.
As for NC, the coke-bottle styling is gone. The NC looks too short & boxy, the body lines just don't blend as those of the NB. I just can't warm up to those cumbersome fenders. The NC over-styled dash just doesn't have the simple elegance and retro-look of the NB.
No offense to NC owners though
