d5200 is as good as the d600!

I scanned thgrough this thread hoping to learn the pros and cons of D5200 images to no avail.

Since I use the d5100, what I'd like to know is: are the images noisier than d5100 images for same lighting and iso settings?; are they sharper for the same lens i.e. better sensor discrimination?

Anybody know?

Thanks.
