Samsung announced two flagship Android smartphones for 2015, the Galaxy S6 and the Galaxy S6 edge.
Both devices are available now, although you might have to wait until 24 April if you're getting the SGS6 edge SIM free from Samsung. Once you have decided which is the handset for you, check out our best deals feature to find the right contract.
The Galaxy S6 stands out from previous generations, and there are a number of key features that set it apart from its competition, while its stablemate - the new Galaxy S6 edge - takes things to entirely new level in terms of design.
But which is the handset for you?
Same size and resolution display, but different designs
The Galaxy S6 features a 5.1-inch Quad HD Super AMOLED display (2560 x 1440) that features a pixel density of 577ppi, which is the same as the Galaxy S6 edge that also has a 5.1-inch Quad HD (2560 x 1440) Super AMOLED display. The Galaxy S6 has a standard display, while the Galaxy S6 edge features a dual-edge design.
The Galaxy S6 edge as it is a little different, although it doesn't offer as wide functionality as the Note Edge did. There are a few clever features, as well as the wow factor in the design. It's the wow factor that appeals here, because the S6 edge is unique.
Both displays are good. They offer excellent visuals, with inky blacks and pop and vibrancy to colours, although the whites aren't as clean as some. The S6 edge wins out though, as it's just a little bit more special.
Galaxy S6 is slimmer, but Galaxy S6 edge is lighter and quirkier
Samsung finally ditched the plastic body for the Galaxy S6, in favour of an aluminium frame with glass for the front and back panels. The Galaxy S6 edge carries a similar metal design, but it has that dual-edge display, which is the most obvious difference in the two models.
The Galaxy S6 measures 143.4 x 70.5 x 6.8mm compared to the Galaxy S6 edge's dimensions of 142.1 x 70.1 x 7.0mm so the Galaxy S6 is slimmer, but has a slightly larger footprint, although we are talking a millimetre and under here. In terms of weight, the Galaxy S6 weighs 138g, while the Galaxy S6 edge hits the scales at 6g less.
Both the Galaxy S6 and the Galaxy S6 edge are available in a wide range of colour options, including white pearl, black sapphire, and gold platinum. The Galaxy S6 has an additional blue topaz colour, while the Galaxy S6 edge has a green emerald colour.
Same camera on Galaxy S6 and Galaxy S6 edge
Both the Galaxy S6 and Galaxy S6 edge feature 16-megapixel rear cameras, both have an aperture of f/1.9, designed for better low light shots, as well as Auto HDR. The two devices also have a 5-megapixel front camera, which too features an aperture of f/1.9.
The camera performs really well and the devices are matched in terms of capability. Fortunately, it doesn't matter which you choose, as it's one of the best performing cameras you'll find on a smartphone, so a safe bet either way.
The best bit is the double-tap on the home button to launch the camera - it's really handy.
Galaxy S6 edge has a slightly bigger battery
The Galaxy S6 features a quad 2.1GHz octa-core processor and 3GB of RAM, the same as the S6 edge. They are snappy and really fast, offering a great experience.
When it comes to storage, the Galaxy S6 will come in 32GB, 64GB, and 128GB on-board storage variants, with no microSD card support. The S6 edge is launching at 64GB with 128GB option.
Despite these two handsets offering relatively similar specs so far, there is a slight difference when it comes to battery capacities. The Galaxy S6 offers a 2550mAh non-removable battery while the Samsung Galaxy S6 edge has a very slightly bigger 2600mAh capacity.
Both devices have wireless charging and while it makes sense that the edge has a larger capacity given the design of its screen, this doesn't really translate into much of a difference when it comes to endurance. If there's one downside of these two handsets, it's that the battery isn't the best performer out there.
Android 5.0 Lollipop on both flagships
The Galaxy S6 and Galaxy S6 edge will run on Android 5.0 Lollipop straight from the box, along with a lighter version of its TouchWiz interface, which has been tweaked and refined to be less intrusive than ever before.
The Galaxy S6 edge also has some extra software features that take advantage of its design. Check out our Galaxy S6 edge tips and tricks feature and you can see some of the software changes that the S6 edge offers.
The Galaxy S6 edge is more expensive
The Galaxy S6 will cost £599.99 SIM-free for the 32GB model, while the Galaxy S6 edge will set you back £760 for the 64GB model so you pay quite a bit more for that dual-edge design, accepting the increase in storage.
In terms of contracts, the Galaxy S6 is available on two-year plans starting from £31 a month, although you have to be an existing Virgin Media customer to get it this cheap, most sit more in the region of £38 a month. The Galaxy S6 edge is around £5 more a month than the Galaxy S6 contracts, starting around £43 a month.
Both devices are mostly the same in terms of specs and the experience from both devices is excellent: whichever you choose, you're getting one of the best Android experiences around.
So this decision really doesn't come down to the specs. There's so little difference in performance and capabilities that this is really about that design. The curved edges to the S6 edge's display will be a talking point. There's the slight feeling that Samsung could have done a little more with them in terms of interaction, but they don't half look good.
The regular Samsung Galaxy S6 on the other hand is entirely dependable. It might not have the fancy pants display additions, but it's every bit as capable and it leaves you with a little more cash in your pocket as it's cheaper.
So the real question is this: do you want your phone to be a talking piece, or do you just want it to be a great phone?
