So far, 2014 has been a great year for smartphone buyers, as technology firms around the world released a wave of top-end handsets that make 2013's offerings look like children's toys.
Both handsets are excellent for personal and enterprise use, each coming with custom, never before seen technologies and features, as we noted in our Galaxy Note 4 and iPhone 6 stand alone reviews.
However, as most buyers want to shell out for only one handset, many tech fans have wondered which smartphone would be most worthy of their hard earned cash.
Design and build
Visually, the iPhone 6 and Galaxy Note 4 are about as different as you can get. On the one hand this is down to the two phones' vast disparity in size. The Galaxy Note 4 at 154x79x8.5mm and 176g makes the iPhone 6 look downright minuscule at just 138x67x6.9mm and 129g.
But more importantly, it's due to Apple's decision to build the iPhone 6 chassis entirely out of metal. For us, the use of metal is a big deal as it makes the iPhone 6 feel significantly more classy than the Galaxy Note 4, which features a removable leather-finish polycarbonate back.
In your hand, the smaller dimensions and rounded sides of the iPhone 6 make it noticeably more comfortable to hold than the Galaxy Note 4, which requires two hands to wield, especially if you have dainty hands.
That said, despite being made out of metal the iPhone 6 doesn't seem as drop or scratch resistant as the Galaxy Note 4, and the polycarbonate backplate proved significantly more damage resistant than the Apple phone's metal one.
After using both handsets we found that the iPhone 6, like past iPhones, has a tendency to pick up scratches and marks when used without a case.
Winner: iPhone 6
Despite assurances from Apple that the iPhone 6's 4.7in, 1334x750 HD, 326ppi Retina display is the best ever seen, the Galaxy Note 4 has a definite edge. Featuring a 5.7in 2560x1440, 515ppi Super Amoled display the Galaxy Note 4 has one of the highest pixel per inch densities ever seen on a phablet.
Running the two smartphones head-to-head, however, we found the fight closer than we expected. Thanks to the use of IPS technology, whites and colours displayed on the iPhone 6 were richer than those on the Galaxy Note 4, and the Apple handset was noticeably brighter.
That said, with prolonged viewing, we did begin to notice a difference in sharpness between the two and found text and icons on the Galaxy Note 4 slightly crisper than the iPhone 6, although we noticed this only after staring at the two smartphones sat next to each other for longer than we'd care to admit.
The extra screen real estate on the Galaxy Note 4 was another differentiating factor that aids the Android handset's productivity appeal, making it easier and more pleasant to do things like read and edit documents or watch videos than on the iPhone 6. More on this later.
