Right now? Yes, because I prefer the black bezel.
On my 6+, because it's sleeker and has a more professional look. It speaks of class and looks sexy too. Plus, I knew I would be looking at this screen more often than past phones, so the black is key for me.
On my iPad, because the black bezel doesn't compete with the screen. It simply disappears.
My MacBook Pro bezel is black, so it's just keeping with the same experience for me.
