[Galaxy Note 3 Q&A, Help & Troubleshooting] katamari201:
You know the LG G2 and Note 3 are in two different product categories right? There is a big size difference between the two. You have been using sub 5" phones. Have you tried out a phablet at the store? Borrow one to try out and pocket? The LG G2 is no bigger than last year's Galaxy S3 and packs a 5.2" whereas the Note 3 is still very much a phablet and bigger than the Optimus G Pro.

They use two different screen technologies. Do you want Super AMOLED or IPS LCD? It makes a big difference for some people. Check it out at the store.

Do you want removable battery and microSD? The LG G2 has none of these, but that makes the phone unibody and more durable, no annoying seams and creaks. The Note 3 has both, but you have to deal with a flimsy back cover. I've owned nothing but Samsung phones for the past few years. I really hate the creaky back covers that eventually get loose and aren't flush anymore.

Do you want a stylus? Have you tried using it? I've owned the Note 1 and 2 and beyond playing with the stylus for a couple hours, never pulled it out again. Some surveys out there say 90% of Note owners don't even use the stylus at all. The stylus is way too small to hold for me and the button impossible to push. It's slippery and unnatural when writing on the screen. No friction. The accuracy isn't much better than a finger either, so don't expect to be able to scribble really small text or fit more than a few words per line, or do anything more than doodling. I'm not a big writing or doodling person, and you might find it useful, but I'd rather type out something on a keyboard, or quickly finger a note (the LG G2 has quick note taking apps as well) than have to pull out the stylus and clutch the thin stylus.

The reviews of the LG G2 have shown some pretty great battery life. Lg has G-RAM, which saves battery on a static screen, and also packs 3000mah in a 5.2" phone. LG's ROM doesn't seem as bloated as Touchwiz either. The Note 3, which is a whopping 0.5" bigger, only upped the battery by 100mah to 3200mah from the Note 2, and doesn't have G-RAM. a Full RGB AMOLED panel at 5.7" is gonna suck a lot of battery, especially when at max brightness. All signs point to the LG G2 having the better battery life.

Both have 13MP Exmor RS cameras made by Sony with optical image stabilization. They are about as good as the OIS in the HTC One, basically not very good. It is no where near the kind of smoothness the Lumia 920/925/1020 can achieve. It is because they aren't willing to go the extra mile and make the camera module bigger for better OIS. The pictures are roughly the same, since they are they same sensor after all. It's down to which type of post-processing you like more. The LG G2 has a nasty autofocusing issue in video that makes the image bounce around like a diaphragm. It may be fixed by release time (or not).

Do you like side buttons or buttons on the back? You'll have to try the LG G2 out in person to see if you like the back buttons. Do you like on-screen buttons or Samsung style shoved to the bottom buttons? I'm not a fan of onscreen buttons, but LG's ability to customize them, as well as the infinitely useful double tap to turn on, are turning me around. I honestly hate the home button and the shoved down to the corner capacitive buttons on Galaxy phones. How many times have I backed out of the camera or screwed something else because of accidental button presses? And going from soft taps to a hard push for the home button is still jarring. It's not a quick or reassuring process. Apple makes way better home buttons than Samsung.
