Have flown both window and aisle Sky Suite seats on the 773. Personal preference is aisle - I found the window seats (and by similar design the center J seat) to be very claustrophobic. They are very tight in the shoulder area and no real storage space (except for a netted shelf above your head). The aisle seat isn't without it's issues. The shelf/storage space next to the seat is nice (this is the space where the power and audio jack are located). The only complaint I have is that you have to contort your body to actually reach it as it is partially blocked by the seatback. Perhaps my seat was not adjusted correctly (I had my seat in the upright/work/dining position), maybe I needed to move the entire seat back? The storage under the ottoman was great for large backpack, shoes, etc. Honestly, my preference in the reverse herringbone J class seat.
