If you pretend that you’ve thrown out all your other bands (or never got them in the first place), it’d be a simple choice for you? I think that’s true for me too.I’m in the same boat, I love my Series 2 white edition but really am into the new grey. I’ve got a ton of bands so a series 3 white makes the most sense but I prefer the subtlety of the grey.
Even though the soft white sport band definitely blends/looks better with the white series 3 ceramic than the cloud color that came with the series 2 ceramic, I think I’d choose the gray if I had no previous investment in bands.
