However, because the two flag-ship haven't been unveiled, we just can make a comparison based on the news and rumors.
Design and buildI think many people will pay attention to the appearance of them firstly, just like me. Indeed, the build and design of Samsung Galaxy series phones are not my cup of tea. There are no any more differences between every Samsung Galaxy phone except for size of body. However, some rumors said that, Samsung Galaxy S5 will have a different design and build. The rumors are well-founded, we can find the change in the previous flag-ship of Samsung Galaxy-Samsung Galaxy Note 3, which has a fur rear. Based on the rumors, Samsung Galaxy S5 may be built with metal in body, and the design also is different from "cobblestone". There are many concept pictures of Samsung Galaxy S5, you can learn from them, but Whats is the final version? We just can wait for its release date.
On the other hand of iPhone 6, even after the release of iPhone 5S/5C, some leaked geeks have posted the so-called iPhone 6 design pics. As a matter of fact, the design of iPhone 6 is still a mystery. What we can confirm is that iPhone 6 will be bigger and loner than its brothers. What we can also say is that the company is well known for utilizing premium materials for its flagship device. The iPhone 4 and iPhone 4s were comprised of plastic, glass and metal. The iPhone 5 and iPhone 5s used anodized aluminum and glass. Suffice to say, it would be strange to see Apple take a step backward with its build materials and its form factors.

UI-ever for iPhone and coming for Samsung Galaxy S5Apart from the appearance of body, another objective design is necessary to be considered. The UI of Samsung Galaxy S5 have been confirmed to have a new design. Based on the pictures, the whole style of the UI seems quite different, colors are dull than former UI of Samsung's phone, more technical and more mysterious. By the way, Samsung is designing a new UI named Tizen for their smart phone. Samsung Galaxy S5 is possible to have a Tizen version.
Since iOS 7 release, we have saw the changes of iPhone' UI, many guesses announce that there may be no more changes in iOS 7 for iPhone 6. Some optimizations are possible. In my opinion, the design of flat in iOS have been on the top of the tide of fashion, it is wonderful enough so far.

Display and CameraThe most rumors said that the new Samsung Galaxy will come with a display that is in the vicinity of 5.2-inches. It just is sightly bigger than Samsung Galaxy S5. Nice! A Russian blogger Eldar Murtazin who said that the Galaxy S5 would sport a display with 2560 x 1440 resolution with 560 pixels-per-inch. 2K display, right? If it is true, Samsung make a "monster" again and again!!
About display, iPhone is like a "solitary man" away from the fashion of big screen.iPhone may follow the fashion in iPhone 6, which may be bigger. However, all of newses are just rumors, I prefer to believe iPhone will have 1280 x 720 display resolution.
There are less news about iPhone 6's camera, but based on the concept of Apple, the change of camera in iPhone 6 won't be more, it’s still using an 8-megapixel iSight back-illuminated sensor (BSI) with some clever tweaks to pre and post capture processing and a True Tone dual-LED white/amber flash.
Samsung has confirmed that its 2014 flagships will be carrying the company's own 16-megapixel ISOCELL sensors, but these aren't expected to debut until later in the year. Currently the firm is testing an 8-megpixel ISOCELL which is expected to appear in the Galaxy S5.
Other hardware and software featuresMany fans of Apple or Samsung are looking forward to there are many new high-techs can be found in iPhone 6 or Samsung Galaxy S5. Although many sources are guessing the specs of iPhone 6 and Samsung Galaxy S5, guesses just guesses. As the flag-ship products in every series, both of them won't be disappointing.
It is reported that Samsung Galaxy S5 will have a powerful CPU with 64-bit core and 4G RAM. Obviously, Samsung want to Galaxy S5 have the same performance with iPhone 5S. Another amazing thing is Samsung Galaxy S5 may be added the feature of touch ID that also will occur in iPhone 6.
Finally, some other odds and adds in specs will certainly exist in the two gadgets, we don't need to think too much. Just wait in patience!!
