5. Samsung Galaxy S5
The Samsung Galaxy S5 is a top phone, that's why it's made it into the top four, and it's jam packed full of tech to keep your on the cutting edge.
It's got a fantastic 5.1-inch display, super fast Snapdragon 801 processor and a high performing 16MP camera.
There are also some more unusual additions including a fingerprint scanner hidden beneath the home key, a dust and waterproof chassis and a heart rate monitor on the back - pretty pointless but fun to show off.
The Galaxy S5 loses marks for its all plastic design which results in it feeling a little toy like, and the heavy TouchWiz UI which comes with a whole heap of bloatware.
If you opt for the Galaxy S5 you will be very happy with what you get - especially if you're a Samsung fan - but it you want something which feels as premium as its price tag take a look at the top three entries.
4. OnePlus One
It's probably safe to say that the OnePlus One took almost everyone by surprise. It arrived with little fanfare from a new company, yet it turns out it's one of the top three phones on the planet.
With a full HD 5.5 inch display, 2.5GHz quad-core processor and 3GB of RAM it's got the specs to compete with anything else out there, but what really makes it stand out is the price, because at just £229 SIM-free it beats out the Nexus 5 as the best value high end phone available.
In fact it's roughly half the price of competitors like the HTC One M8 and Samsung Galaxy S5, so with that in mind it's easy to forgive the lack of a microSD card slot and the questionable call quality, and with its tweakable CyanogenMod OS it's even a little bit different.
When it comes to sheer value for money it's hard to beat the OnePlus One. Its build might not be as high end as the HTC One M8 but for what it costs we're surprised it even has a screen.
Speaking of the screen, it might be a little on the large side for some users and price aside the phone isn't quite up to the standards of the HTC One M8, LG G3 or the Sony Xperia Z2, but it sure comes close.
3. Sony Xperia Z2
Sony's back in 2014 with an excellent phone in the shape of the Xperia Z2. And the good news is it's impressive. Really impressive.
The industrial design is a little chunky but oozes premium quality in a way that Samsung's plastic shell doesn't, and it's a little more robust than its Galactical and Primary rivals thanks to being IP58 rated.
Great battery life, strong power and a good camera all are present and correct with our new top three phones, but Sony steals second simply by being a great all-rounder. It doesn't have the polish of the HTC One M8, nor the more functional UI, but it does what's asked with top-end specs. That's what we like.
With front facing speakers, a new screen with better colour reproduction, 4K video recording and inbuilt noise cancellation the Xperia Z2 is a great device that should be right on your possible upgrade list.
Make sure you check it out in-store before purchase, as some won't like the larger build, but for a good all-round experience the Xperia Z2 excels.
2. LG G3
The big selling point for the LG G3 is its display. It's the only smartphone on the UK market to sport a QHD (that's 1440 x 2560) resolution, making it pin sharp. While there's not a huge amount of content to take advantage of that res just yet, you can be safe in knowledge the G3 is future proof.
Away from the screen and things are still good for the G3 with a punchy 2.5GHz quad-core Snapdragon 801 processor, 3GB of RAM and an Adreno 330 GPU ensuring the interface, widgets, apps and games all speed along at a rate of knots.
The design is a little questionable with a faux-metal rear, and the 5.5-inch display means the G3 is a little on the large side which will put those with small hands off. Get past those small facts though and this is a top quality smartphone with a boat-load to offer.
If you want the latest and greatest screen technology in the palm of your hand the LG G3 is the smartphone for you, but the whole package isn't quite there.
The LG G3 is a great handset that's more phablet than phone - and it's only slightly let down by lacklustre design.
1. HTC One M8
We love the speed of the camera, the Duo Camera is smart as a tack, the Boomsound upgrade is impressive and the design... well, you have to hold it. The HTC One M8 is an excellent package
The Snapdragon 801 processor has boosted battery dramatically, and that means that photos also process much more quickly as well - even the front-facing camera is much better.
Gaming, movies, photography, browsing all work really well, and in a phone that that's easily going to destroy whatever anyone else can design, unless Apple or LG have got some dark sorcery up their sleeves when the iPhone 6 or LG G3 appear later in the year.
The only way to know how good the HTC One M8 is, is to go into a store, pick it up and hold it for a few minutes. Take in the design, listen to the BoomSound speakers and glide around the Sense UI.
Of course the One M8 won't be for everyone, and the Xperia Z2, OnePlus One and Galaxy S5 are seriously tempting propositions - but anyone looking for the perfect fusion of design and features need look no further.
