Those screw mount Leicas were a pita for me to load unless I cut a leader for them. Liked the Canon P better for that reason plus the thumb wind and nicer VF. Liked range finder cameras quite a bit including the Nikon S2, Contax II and M4/M4P Leicas too.
Favourite SLRs were the Nikon FM/FE series and the F2. Continued to use some of the older manual focus lens on the D700 after I stopped using film. In some ways I liked using those older film cameras more compared to modern digitals but time marches on. I guess it is like the experience of using a SR compared to a cart, that sort of thing mostly.
