In terms of the display, both have advantages and disadvantages. You're basically comparing apples and oranges since they use two completely different display technologies.
The Samsung Galaxy S3 uses a Super AMOLED display which is a newer technology, although not perfected yet. In 2016, OLED will dominate the TV market whereas LCD will be old technology. Super AMOLED produces more vibrant colors, higher contrast and is more pleasurable to look at.
The HTC One X uses a Super LCD display which is an improvement over old LCD display technology. It is significantly better than other smartphone displays which utilize LCD technology. LCD produces more accurate colors.
However the display is not the main deciding point between these two phones.
The main deciding point is the UI, smoothness, functionality and performance and the Samsung Galaxy S3 absolutely destroys the HTC One X in these factors. The SGS3's UI is much smoother and the software is much more optimized. In many benchmark tests, the SGS3 dominates.
The HTC One X is not a laggy device but it's full of bugs and quality control issues.

What this basically says is that the Samsung Galaxy S3 has the fastest web browsing speeds on the market. This could be due to the SGS3's superior software engine and better signal transmission hardware. The HTC One X is not far behind though and is much better than the HTC Sensation and Sony Xperia S.

Image quality
Both the Samsung Galaxy S III and the HTC One X feature 8 MP cameras that are capable of taking photos at max resolution of 3264x2448 pixels. Both feature single LED on the back and, thanks to their zippy processors, both offer 1080p and 720p video recording with simultaneous image capture.
The lens used in the Galaxy S III has a slightly wider filed of view compared to the One X.
So let's dive right into the image quality. You'll notice that the weather wasn't identical for the two contenders, but lighting conditions were similar enough to make the images comparable.
We added the Galaxy S II to the first round of tests for good measure.
As you can see from the crops, in good lighting the Galaxy S III tends to produce images with more detail than both its predecessor and the HTC One X.The processing of the new Samsung flagship is much more mature too - it introduces very few oversharpening artifacts and loses little detail, while still managing to keep the noise under control. The One X on the other hand is a bit too aggressive with the sharpening and isn't doing nearly as good at removing the noise.
Both contenders tend to oversaturate colors (particularly green), but
the Galaxy S III comes a little closer to reality.And there go a couple of more shots, which tell a similar story. Differences aren't huge, but the Galaxy S III still has an edge.
We also tested the photos that the One X and the Galaxy S III captured, while recording video. They are 6 megapixel stills in 16:9 aspect ratio.
It's interesting to note that the HTC One X frames pictures differently from the video so you always end up with a result with a wider field of view. The Galaxy S III in-video shots have the same framing as the video.
In good light, the two smartphones resolve about the same amount of detail here, but
the One X has better contrast and it sharpens its images more aggressively, which makes its output look punchier. The Galaxy S III still has slightly better color reproduction, though.
Things get vastly different in low light, when the bright F/2.0 optics of One X count big time.
In such conditions the HTC flagship crushes its opponent, producing images with far less noise and much better contrast.
Most devices out there offer HDR mode straight out of the camera app and so do the Galaxy S III and HTC One X. The One X produces more dramatic looking results, while the Galaxy S III has a pretty subtle approach.
Which solution is better is strictly a matter of personal preference, but the Galaxy S III does resolve more detail and its highlights aren't as exaggerated.Photo quality comparison
We have the Samsung Galaxy S III and HTC One X in our Photo comparison tool. The tool's page will give you the full details and it's where you can make the most comprehensive observations on the cameras involved in this shootout.
The Galaxy S III uses its resolution advantage to easily outdo the HTC One X in the first two charts. The two are much more evenly matched on the last studio challenge, but the S III shot has far less noise there.

We were pleased with the video capture on the HTC One X. But the Galaxy S III is just too good to compete with - the resolved detail in the Galaxy S III videos is incredible and they are very smooth with accurate colors.
Here's the Galaxy S III 1080p FullHD sample.

And the One X 1080p video sample.

There's also the bitrate to take into account.
The HTC One X videos come out with a relatively low bitrate of about 10 Mbps, while the Galaxy S III's clips hover around the 17 Mbps mark. Both devices offer stereo sound recording during capture. Below we've lined up 720p video samples by each of the devices.

The lower bitrate is evident here as well.
At 6Mbps the One X videos have about half the bitrate of those captured with the Galaxy S III. (Galaxy S3 is the winner)
http://www.youtube.com/watch?v=Ee0qO4Z9u2cOverall, it's hard to see beyond the Samsung I9300 Galaxy S III for the winner in the video recording category. The One X shoots decent videos, but those are nowhere near the S III standard.
