Just use the thing and enjoy it. It won't take better pictures than a C/V Bessa -- a lesson that's worth learning in and of itself -- but you'll enjoy learning what all the fuss re "Leica feel" is about. (And it may be enlightening to discover that you don't really consider it such a big deal, allowing you to cross a Leica off your own personal wish list.)
Re the lens, I doubt if you'll see any difference vs your CV lenses in "quality" (whatever that means) but it might be interesting for you to see how its character differs from the lenses you're used to.
To do that, try some of the kinds of shooting you're used to, but also push the envelope a bit: shoot at full aperture, shoot into the light, include drastically out-of-focus areas in the foreground or background, etc., etc. It's when you get onto the edges of photographic technique that the "personalities" of different lenses begin to shine through.
PS -- Don't be surprised if you decide you like your CVs better -- Cosina makes terrific lenses.
