Definitely!
… I like the size of the screen on the Galaxy more than my I Phone, but of course the 6 has a larger screen.
… If you have Apple computers/I Pad's then I'd guess the I Phone would be better at the photo thing....
… if you can find something used that you know works, I'd settle for something a model or two old and save a chunk of change.
The
iPhone 5/5S screen size is a 4 inch (100 mm) diagonal with 640×1136 pixel resolution, and has a ~1560 mAh battery.
The
iPhone 6 has a LED-backlit IPS LCD Display that is only slightly larger at 4.7 inches with 1334x750 pixel resolution, and has a 1810 mAh battery.
The
iPhone 6 Plus has the same type of screen, but is considerably larger, at 5.5 inches (diagonal) and 1920x1080 pixel resolution, with a 2915 mAh battery. The thickness is slightly increased from 6.9 to 7.1 millimeters on the iPhone 6 Plus. This model can be a handful. (If they make the next model much larger they might as well call it an iPad mini!)
The
iPhone 5/5S uses digital image stabilization, and can shoot HD video (1080p) at 30 frames per second or HD video (720p) at 120 frames per second.
The
iPhone6 includes
optical image stabilization and can shoot 1080p video at either 30 or 60 frames per second. The camera also includes phase detection autofocus, and can record slow-motion video at either 120 or 240 frames per second.
Storage options: 16, 32, or 64 GB on the 5/5S; 16, 64 or 128 GB on the 6/6Plus.
Shortly after its public release, it was reported that the
iPhone 6 Plus chassis was susceptible to bending under pressure, such as when carried tightly in a user's pocket; the iPhone 6 appears to be unaffected by the issue. That could be seriously worse than "butt dialing"!
I would strongly recommend using a belt holster for any iPhone, rather than stuff it into a pocket, and fumbling for it from there.
While you can certainly "save a chunk o' change" with an older model, you should be aware that many of the app developers quickly abandon support for the older models (older OS versions), which can leave you twisting in the wind.
