The LG G3 is entering a really rather packed smartphone market, and these are the big phones you'll probably be considering over the South Korean's big hitter – take a look to see how it stacks up against the best the competition has to offer.

Samsung Galaxy S5

Samsung's had a little bit of a swing and a miss with the Galaxy S5, as while it's a great phone with a lot of power, it still pushes too hard on the gimmicks with a low-quality chassis compared to the rest.

The screen quality is high thanks to the Super AMOLED on show, but I'd say LG still shades it with the higher resolution, if not the brightness or contrast. If you want the best of both then you can always hold out for the Galaxy Note 4.

In terms of design the LG G3 is ahead, especially when it comes to looks, and the brushed metal effect doesn't feel too bad in the hand – plus there's no faux chrome.

LG's simplicity trumps Samsung's efforts with things like the heart rate monitor – I get the feeling Samsung is going nail the health market in the future, although not with this phone. The S5 is also waterproof, which is much less of a gimmick, and something it's interesting LG opted not to do.

iPhone 6 Plus

Apple's out the gates with its first phablet and it's got an LG G3-matching 5.5-inch display. It's a strong first attempt too, with a 401 pixel per inch 1080p screen, sporting impressive viewing angles, great contrast and bright colours.

I'd argue that it's not quite a match for the LG G3's display though, thanks to that phone's crystal clear QHD resolution.

The iPhone 6 Plus certainly trumps the LG G3 when it comes to looks though, with a truly premium body and it also gives the LG G3's camera a run for its money.

But despite its high-end appearance, the design of the iPhone 6 Plus makes it more awkward to use one-handed than the LG G3, as it's both taller and wider. Its biggest problem though is its price tag, because with a starting price of £619 it makes the LG G3, which can now be found for under £400, look positively cheap and it's hard to justify the extra expenditure.

HTC One M8

The best phone on the market doesn't have anything to worry about from LG – but it's not miles and miles ahead.

The metal construction, mature overlay and focus on the key elements of sound and general user friendliness abound with this powerhouse of the phone world, albeit not a status that's matched by sales.

That's not to say the LG isn't without charm and plus points: the battery life is superior and the pictures that it spits out are of slightly higher quality.

The design doesn't hold a candle to HTC, and the user interface isn't as powerful, but if you value power and specs over a more balanced phone, the LG G3 isn't a bad choice.

iPhone 5S

The difference between the iPhone 5S and the G3 is stark – one is compact, the other massive. LG reckons that the Retina display has had its time in the sun, and it has found the ultimate screen resolution – yet Apple stuck with Retina HD for the iPhone 6 and 6 Plus.

The iPhone 5S probably has a more robust camera that's a little simpler to use and handle, and the app selection is improved. But everything from a faster OS to a better screen and improved audio experience swings things in LG's favour.

Sony Xperia Z2

It's a tricky one to decide whether to recommend the Sony over the G3, as both are rather large handsets with the same powerful innards.

The screen quality on the Z2 is appreciably better than Sony's efforts in 2013, and the user interface matches LG's in terms of simplicity.

The cameras go toe to toe as well, although Sony's odd predilection for noise in lower light snaps is still a conundrum I'm trying to work out – the company drafted its camera team to improve the sensor, so to have that miss is odd.

In terms of design the Z2 is definitely superior – it's slightly more compact in the hand (although it is tall) and the glass / aluminium casing feels really nice too.

This is a tricky one to call – I'd suggest trying both out if you're torn or hold out for our Sony Xperia Z3 review and consider that instead.
