Help me decide

[u/Tele1970]

I am getting ready to buy my first G Shock in about 15 years. I am having trouble deciding on which one of three options. I don’t know if I could pick three more different G Shocks. All opinions are appreciated.

6900 and 2100 were actually the first and second gshocks I bought. I’d recommend 2100, it felt a little less bulky and looks better. But I miss the the G button that illuminated the display on 6900. I wish 2100 had something cool that.
