Speaking for myself, I have and use many types of cameras - SLR -Rangefinder - TLR - Folder - Full automatic point and shoot.
Most times I prefer a rangefinder. My favorite cameras are a lowly Zorki 1, Zorki 4, Exa, Exakta VX, Canon IVSB2, Leica IIIf, Minolta Autocord, Yashica 44, Franka Solida II.
NOTHING feels the same as the Leica. Nothing sounds the same as the Leica. The Canon is a gorgeous, excellent camera but I hate the way the shutter sounds and the 'feel' when the shutter is released. Other than that, it is every bit as good as my Leica - maybe better.
But the Leica just feels right. The finish, the balance, the fit, the sound, the weight, the speed at which I can use it.
