There is more legroom at the over wing exits on the 737-800 than there is in the forward cabin extra legroom rows on the 757-200.
There is an extra tray table for the arm rest of the 737-800 exit rows as the seat in front is a bit of a stretch to use the tray table.
The over wing exit rows are better than the extra legroom at the front. No one invading your space whilst queuing for the loos.
