Samsung Galaxy S7 review:

THE GOOD Polished design. Awesome camera. Long battery life. microSD storage slot and water-resistant (again!).

THE BAD Annoyingly reflective. Smudge magnet. Plastic-looking selfies even with no filter. No removable battery, which isn't surprising, but is still a compromise compared to 2014's S5.

THE BOTTOM LINE The fast, powerful, beautiful Galaxy S7 phone is 2016's all-around phone to beat.

Apple iPhone 7 review:

THE GOOD Improved front and rear cameras -- now with optical image stabilization -- deliver much improved photos, especially in low light. Water resistant. A faster processor, plus slightly better battery life. More onboard storage than last year's models for the same price.

THE BAD No headphone jack (but there's a dongle and compatible wired headphones in the box). Click-free home button takes getting used to. Only the larger 7 Plus has the cool dual camera. Shiny jet-black version scratches easily.

THE BOTTOM LINE The iPhone 7's notable camera, battery and water resistance improvements are worthwhile upgrades to a familiar phone design. But ask yourself if you really need an upgrade... and if the Plus might be a better choice.
