This year, Samsung finally shifted away from its plastic designs in favor of a new design language that includes glass and metal. The Galaxy S6 looks a lot like the iPhone 6 but they aren't identical and there are some things that the Galaxy S6's design does better.
For instance, the iPhone 6's all-metal design can, at times, be slippery in the hand. The Samsung Galaxy S6's metal and glass design isn't slippery at all and it will stay in your hand without any problem at all. That's something we've grown to appreciate.
The Galaxy S6 is fairly light and it's thin enough to fit in most back pockets if needed. This is important if your phone rarely leaves your side.
This is, without a doubt, the best Galaxy S design that Samsung's ever put out. We haven't missed the microSD card slot or the removable battery at all.
