Both CNET and The Verge had the opportunity to test out the devices.
To find out, we put the S6 head to head with the iPhone 6 Plus to see how it fared in a variety of situations. As it turns out, the S6 can hang: it’s very close to the iPhone in terms of image quality and detail. The S6 shots are a little warmer, but not offensively so, and the two phones handle low-light a bit differently.

The Galaxy S6 and the iPhone 6 were pretty neck-and-neck. Personally, I’d give the Galaxy S6 the slight edge, since I’m partial to its saturated tones that come off bright without looking too unrealistic (a characteristic that plagued Galaxy cameras before).
