I need a new camera (XZ-1 stolen). Perhaps a micro-four system?

Hello,

I need a new compact camera and i don't really know which one..
I had a olympus XZ-1 and was happy with the image quality (at 100 ISO only).

I cannot decide which new camera i should buy now (my XZ-1 has been stolen).
I am not a beginner (i have a canon 60D and many objectivs) and take most of the time
landscape pictures and my daughter.

I read the review and all forums and found every point of view...
My choice would be between:

- Olympus XZ-2
- Lumix LX 7
- Nikon P7700
- Olympus E-PL5
(The fuji X-E1 or pro are too expensive and have a slow focus)

Do they have all a better IQ as the XZ-1? (Not only at high iso because that's not difficult )

I found the IQ of the E-PL5 good and sharp but... I cannot explain why but too "digital" and not natural.
Perhaps i saw the wrong pictures... The canon G15 also.

The best camera would be for me a camera with great IQ and natural color/contrast and video capability.

Which one could it be?
Perhaps you can send me per mail? samples of picture if you have. (fm29@gmx.net)

Thank you in advance.
