HTC One M8

The HTC One M8 is currently sitting atop our "best mobile phones in the world" ranking, nudging the Galaxy S5 into second place and making it the phone to beat in 2014.

Does the Sony Xperia Z2 topple the M8? Honestly, no. As a complete package the One M8 wins out, but the Z2 still has a couple of things over its Taiwanese rival.

A lot has been said about the camera on the M8, and in a straight spec shootout the Xperia Z2 beats it hands down with a 20.7MP snapper versus a lowly 4MP offering.

The Z2 camera doesn't bring anything particularly new to the table though, while the M8 has the innovative Duo Camera setup and a much faster image processing time.

4K video recording is just a distant dream with the HTC, while the Xperia Z2 can pull out some of the best footage you'll see shot on a smartphone.

When it comes to interface, performance and design however the One M8 offers up the better experience. If the camera isn't a huge deal breaker for you then the M8 is the better option, but if you fancy a reliable snapper the Z2 is the way to go.

Samsung Galaxy S5

The Samsung Galaxy S5 is the best flagship the company has produced to date, and independent screen testing firm DisplayMate said it has the best display it has ever tested.

Things are looking good in the Samsung camp, and with a fingerprint scanner and heart rate monitor to help it stand out from the crowd it has a group of features to shout about. Something the Xperia Z2 rather lacks.

While Samsung may well have packed a whole heap of tech into the Galaxy S5 a compromise had to be made somewhere. Build quality.

The Galaxy S5 is undoubtedly plastic, and it severely lacks the premium appeal of the Xperia Z2. Both handsets are waterproof, so it's not like the S5 can use that as an argument.

It's features versus form here, which one is more important to you?

iPhone 5S

All the latest flagship smartphones are big. Some people would even call them huge. So what's left for those who want a top of the line handset which isn't going to overstretch their palms?

Top of the pile is the iPhone 5S, with a premium design only really matched by the HTC One M8, although the Xperia Z2 is hot on the heels of both of the handsets.

The 4-inch display on the iPhone 5S is a rather disappointing 640 x 1136 affair, no where near as stunning as the full HD Xperia Z2.

iPhone 5S

Its more compact design and lower weight (it's only 112g vs the 163g Z2) means the iPhone 5S is far more palm friendly, especially for those with smaller hands.

It is rocking older tech, with an 8MP camera, dual-core processor, 1GB of RAM and no 4K video recording to go with that sub-par screen.

Plus it still costs a pretty penny - the same as the Xperia Z2 - which isn't great value for money when compared.
