Interface and Functionality:

Now here’s where it gets cooking, seeing that LG has finally accomplished some remodeling work with its custom Android experience. At their core, the two opposing custom UIs offer all the foundational aspects of the platform that we adore – like its deep personalization and wealth of widgets. Beyond that, there are stark similarities between their additional features, but when it comes down to it, we find Samsung’s TouchWiz Nature UX to be the deeper, more comprehensive, and practical between the two. Honestly though, we appreciate the evolutionary improvements made with LG’s effort, like its QSlide, Dual Screen/Dual Play, and Live Zooming features, but we find Samsung’s wealth of offerings to be more refined and developed. Specifically, S Voice, S Beam, and Share Shot are some of the myriad of cool features that are not only practical for real-world usage, but the execution is there as well in making it useful for everyday situations.

Taking a quick peek at the core set of organizer apps of both handsets, there’s nothing different about them except for their slightly different looks – albeit, their functions are identical. Furthermore, there’s nothing too out of the ordinary with the native email apps on both devices, as they prove useful in making us extremely productive on the go. However, there are some specific features that stand out with the two – like the screen zooming feature with the LG Optimus G and the “select all” function found with the Galaxy S III. Then again, the Gmail experience is 100% identical.

Giving us plenty of room for our thumbs to play around with, the on-screen keyboards of both Android smartphones enable us to accurately type messages with minimal mistakes. Not only are we presented with spacious layouts, their responsiveness enable us to maintain a steady rate of input.

Processor and Memory:

From a cursory look, one would hardly notice the difference in performance between these two Android titans – mainly due their super responsive actions with all tasks. Whether it’s basic tasks like opening apps to more complex ones like gaming, the two are no doubt on the same pace to each other, but as we meticulously compare the two, we do notice more of a snappy feel with the LG Optimus G. In addition to that, its benchmark scores really tell the true story in how its quad-core 1.5GHz Qualcomm Snapdragon S4 Pro processor with 2GB of RAM is more effective in executing tasks with a sense of rapidness than the Samsung Galaxy S III’s dual-core Qualcomm Snapdragon S4 processor with 2GB of RAM.

With the Sprint versions of the two handsets that we’re checking out, the Samsung Galaxy S III coughs up the usual 16GB of RAM out of the box, which can be supplemented by its microSD slot. The same goes for the AT&T Optimus G. Oppositely, the Sprint LG Optimus G has only 32GB of internal storage with no expandability.

Internet and Connectivity:

Let’s be serious here people, even though there’s an advantage with the LG Optimus G’s quad-core processor, it doesn’t necessarily prove to be a deciding factor in the web browsing experience. In fact, the experience is simply dreamy with the two smartphones, since they offer speedy 4G LTE connectivity and those always-lovable fluid navigational controls. Heck, even relying on their stock browsers that support Flash, they’re able to maintain a responsive performance throughout it all.

Very well known at this point, we know that there are many variants of the two smartphones in this comparison, which means that they’re both available in GSM and CDMA forms – with 4G LTE connectivity in tow as well. Moreover, they share many of the same connectivity features as well, like aGPS, Bluetooth 4.0, Wi-Fi, mobile hotspot functionality, and NFC.
