Choose the Galaxy S9 if you want the phone's premiere radio performance in a more compact size. I'd also keep an eye out for the Sony Xperia XZ2 Compact if you're on AT&T or T-Mobile. It's even smaller than the S9, but it will have slower LTE connections, a lower-resolution screen, and no headphone jack, and we don't know how much it will cost.
The Galaxy S8 was the best phone of 2017. The Galaxy S9 is a little better. The Galaxy S9+ is even better. It's up to you whether the size and cost are worth the power: For us, they are.
