Between me and the exit
I had seen myriad examples of hopelessly inappropriate passengers in the exit row seats so I subsequently readjusted my thinking and gave up on the exit row mess- now it's the aisle seat, last row, right hand side (and many, many boarding stubs to prove it)-and nothing but space between me and the rear door. My money is on the trained cabin crew member stationed there and to me that is worth the loss of a bit of leg room!
