the JLC. It’s fresher and sportier, I can see myself wearing it even with a jeans and t shirt, GO on the other hand even though beautiful to look at, on the wrist to me would seem a bit too classical and outdated and I wouldn’t wear it. Just my personal opinion though, otherwise both are beautiful, no wrong decisions here. Depends on what you are expecting from the watch you are going to purchase and in which situations you’re going to use it
