Wow I’m glad I got the 8+ last year when I did. I always get the silver/white iPhones because when set it down/misplace it, it‘s easier to find. The red iPhone SE would like so much better with a white front.
 
Black to most looks better. It is less distracting when viewing anything with a black background, including video. You also don’t have the border around the display itself.

Plus in promotional stuff it makes the screen appear bigger.
