Samsung Galaxy S4
Like the G2 and the other smartphones in this competition section the Samsung Galaxy S4 is still on sale even though it's been replaced by a newer model.
Samsung packed the S4 full of tricks including eye, head and hand tracking, selling the handset as a "life companion."
Silly gimmicks aside the Galaxy S4 is still a supremely power handset with a lot to offer. It too has been updated to Android KitKat and is enjoying a new lease of life with the latest version of Google's OS.
It's still a little pricier than the other flagships from 2013, but not a great deal so - especially for a handset which sticks so many features under one roof.
The HTC One was the hero of 2013, claiming the best phone in the world title, but the LG G2 pushed it hard.
Like the G2, the One doesn't have a microSD slot, but it does benefit from a superior metal chassis and powerful Boomsound speakers.
Battery life on the One isn't quite as strong as it is on the G2, but HTC's Sense interface and clever camera tricks keeps this year old smartphone interesting.
If you fancy a premium smartphone without the premium price tag the HTC One is still a very good shout.
Sony Xperia Z1
The Sony Xperia Z1 launched a several months after the G2, Galaxy S4 and One, but it's still a decent comparison from the class of 2013.
With a dust and waterproof body, a chassis formed of metal and glass and the inclusion of a microSD slot the Xperia Z1 has some instant plus points over the G2.
The more industrial design of the Sony may put some off, as will the flaps which need to be removed every time you want to charge the device - but the version of Android it's running is closer to the stock Google puts out.
In terms of price there's not too much difference between the Z1 and the G2, with both handsets providing a strong offering.
