This is the case when it is impossible to make a choice. In my opinion both are expressive. And what is more to your taste?

I am colored.

Of course, both options are good. Still, the color looks less dramatic. B / w is perceived more alarmingly. I'm for the color!   

Bb option

It seems to me here under the mood ... Today in color, tomorrow in b / w, the day after tomorrow again in color, etc.

In flower !!!

Both are good, but I like b / w more

Usually, girls-photographers on Instagram conduct such polls: what is better than bw or color?

For me both  but bw is a little more interesting. : super 

I'm for the color! Good day, Sergey!

I am for the color option. The difference is huge. IMHO.
