New
My number one favorite new production camera has to be the Leica Monochrom (photo above.) I know, it probably isn't brand new anymore but it is to me.
After that comes my new M-A. So new I don't even have it yet.
Since it is still in production I guess that the M9 also fits.
Classic
Tied for number one on my personal list right now is the Leica Null. Mine is a limited edition reproduction so perhaps it belongs above, but it is no longer produced. I have to say, if the originals were this fun to use it is no wonder that Leica became so big.
The Zeiss Ikon would have gone to the top until just a few months ago when it was discontinued. I guess it is now a classic, but such a wonderful classic it is. I am sure I'll catch heck for this but I think this is what the M should have become.
Third on the list of favorite classics is my Zeiss Ikoflex Favorit. Though many here favor the Rolleiflex I have to say I am very happy with the Favorit's image quality.
Fourth on my list of favorite classics are the Barnack gems. Any one of them will do, they all have that something special that makes working with them a treat, even today.
Finally comes my Fuji GA645 Professional. It is truly the ultimate point and shoot.
