It's really personal preference. Go to an Apple Store and try each one on if you haven't yet. I tried on the leather loop on preorder day and fell in love with it, so much so that I've bought 2 different colors and am trying to curb a band addiction! But that's my personal preference...you may like the buckle better... So all in all, I say try both on and see which fits and feels better to you.I'm torn between the two, but I'm leaning towards getting the black classic buckle when my 42mm SG arrives. Can anyone recommend one over the other and why?
