Please tell me which one is the best coach seat on AS B734 and B737? I have chosen row 7 on a B734 and row 19 on a Boeing 737-700...What do you think?

I want to see the view through the window (I hate to see that the engine cover the landscape.

I want to have more legroom.

I want to sit on the three seats! (i'm not fat but i need some quiet time!!)
