agree with row 1 - preferably AB as these are farthest away from the galley (otherwise JK, but if the sides aren't available the middle is fine too).
The major benefit is that after take-off - if you have a standard rolla-board cabin bag, you can place this on the floor and rest your legs on it fully horizontally. Makes for the best sleep possible.
