I have an M1 MBA in SG and a 14" MBP in silver. I picked up my M1 MBA used for a stupidly good price so colour wasn't a consideration, but when ordering the 14" MBP I ordered Silver due to the investment, and due to the potential long term implications.
I have a 12.9" iPad Pro in space grey that I've loved for years that has been connected to a Apple magic keyboard or folio, which is completely discoloured on the back side of the iPad Pro. I had also scratched it somehow on the edge shortly after I got it, and the silver underneath shows and sticks out like a sore thumb. the charging port remains unmarked. I generally keep all my devices pristine, so wasn't happy with this and didn't want to risk it with the MBP.
The used M1 was a bargain so the colour wasn't as important, but the cost of the 14" MBP had me go with silver.
