Over the holidays I’m juggling the XS with no case, the Otterbox and the Apple Leather case. After using the Otterbox constantly then going back to no case and back to leather I think the leather one offers me the best grip and size compromises of using a case.

Two things that are downside of the Otterbox, slippery back so it spins around on tables, buttons are stiff and the lower part of the case restricts the up swipe for multitasking.

The leather case offers a smaller footprint, is grippy and no restrictions on the bottom of the case.
