15400 choice dilemma

[Henri1982]

Hi, looking for opinions on the following:

I have the option to buy an unworn 15400 with grey dial and 4 years of warranty. The other option is a 15400 blue dial from 2013, had one service in 2016. I’m only paying 2k more for the blue, and both watches come with complete with box and papers. Condition of the blue is very good, only a few scratches and bezel/screws are not flush.

What would you do?

Thanks so much for the help!
