The iPhone 6s is Better
A lot of people confuse the iPhone 6 and the iPhone 6s, but they are two completely different phones with two completely different futures.
The iPhone 6s comes with several hardware upgrades that make it a better choice than the iPhone 6 in 2018 and beyond.
The iPhone 6s handles iOS 11 better than the iPhone 6. It can shoot better videos and better photos. It comes with 3D Touch shortcuts. And it can take advantage of Augmented Reality applications.
The iPhone 6s will also get iOS 12 and it should get iOS 13 and iOS 14 as well. And like the iPhone 6, the iPhone 6s is extremely cheap.
If you aren't in love with the iPhone 7, iPhone 8, iPhone X, or iPhone SE, we recommend the iPhone 6s and iPhone 6s Plus over the iPhone 6 and iPhone 6 Plus.
