Mirrorless digital camera with the best all around (big sensor, speed, fps, low light)?

Which digital camera would you recommend that is the best well-rounded?
I'm talking
-big sensor
-snapshot speed
-slow motion (high fps)
-low light quality in both video and images

I was looking at the Nikon J1 and V1 but they have bad low light quality.
Previously, I was recommended a Sony Cyber-shot DSC-H55, bought it 2 years ago, and absolutely hate it. It's only good for day time pictures, and the recorded sound is glitchy 95% of the time.
Now I'm looking for a mirrorless model.

I had the impression all mirrorless cameras had APS-C sensors at par with dSLR's. Everything should be the same with dSLR's except for the reflex mirror and pentaprism. If you can't take decent shots with a Cybershot anytime of the day or night then you'd have more difficulty with a mirrorless camera or a dSLR. Skill of the user dictates picture and video quality.

You're complaining about poor sound quality from a compact image capturing device?
