Which is better depends on circumstances and what you prefer.
Row 2: Quicker off the plane, but will likely have more limited overhead space. Row 1 doesn't have any under-seat storage, so everything goes in the overhead, and I've found that the FA's often put their stuff in the first few rows of overhead as well. If you're Mosaic or don't have anything to put overhead, and don't care about EMS, this would likely be the better choice.
Row 11: Better if EMS seats and overhead space matter to you, but much slower off the plane.
