I have mixed feelings about 10A and F. The infinite leg room is great, but the exit door kind of just out into your space, so the legroom depth is great, but the legroom width is about 75% of normal. So perhaps best for super tall and super skinny.
But, as opposed to row 9, there is at least a window to lean against, instead of your seatrow-mate's shoulder if you try to sleep. Row 9 effectively has 2 aisle seats.
Also, 10A and F is very, very cold imo. Power outlets in both rows 9 and 10, though.
Upgrades aside, I'd rank my 757 preferences as:
1. Row 9BCDE
2. Row 10AF
3. All bets are off from here
I agree that these planes are pretty much bottom of the barrel, but unfortunately used exclusively on the routes I fly.
