Beauty is in the eye of the beholder.
But from a specification point of view (contrast ratio and viewing angle) the MB screen is markedly inferior to that of the MBA or MBP.
As someone that works on a notebook 8-12 hours a day, I have a definite preference for the MBA, followed by the MBP and then way at the back of the pack the MB.
I can use any of these machines for business use all day long under optimal conditions. But the MB's viewing angle is very narrow that makes it hard to maintain a viewing position that keeps the screens brightness from top to bottom consistent. It's extremely glossy screen complicates this as when you adjust the screen angle to avoid ceiling lights you end up looking at a screen thats lighter or darker at top or bottom. And its very low contrast ratio makes most blacks actually gray - ok for text but harder on the eyes, and unacceptable for all but the most casual use for multimedia applications.
Adjusting the color profile can make it "look" a little better but actually helps none of its problems.
That said, if it looks good to you - go for it!
