Since this early green is my favourite of all colours, I can't but say "colour, please!"
The b+w looks like they were blooming trees with white or bright pink flowers, and I only realised they were my favourite green leaves in the second... so colour for me. And keep it!
For me it's definitely the color one. The B&W looks surrealistic to me with its almost white leaves. (Is that what you wanted?) And its benches are so dark that I didn't know what they were until I saw the color version.
