The Bessa R has an excellent finder: many would say that it the equal of the Leica M's. And of course, it has behind the lens metering, which will require a large investment with a Leica.
But the Bessas keep reminding me that they are mostly plastic, and if that is a problem for you, the Canon P is an excellent choice. It has parallax-compensating frame lines for 35, 50, and 100mm lenses. The finder is also 1:1, which I don't think any Leica achieved.
Then there is the Canon 7, which is basically a Canon P with a light meter and a switchable finder for 35, 50, 85/100, and 135mm lenses. It has lots of great features, but is not as pretty as the model P.
