The best 35mm camera means different things for different people.
No 35mm camera is a "Jack of all trades, master of all". The Nikon F series tries to be that, but ultimately fails short on some accounts. As an example, if it is need a light weight, strong body camera for hiking, no Nikon F can be called light weight, although the last of the F series, the F6, tried very hard to be that.
Personally, different cameras and/or systems are better than others for some of the photography I do. At the moment, the Nikon EM, or the Nikon F75 if I need AF, is the best for what I am doing.
