Actually, neither layout is ideal..With an off centre layout you are going to have all sorts of problems, particularly with surround sound and acoustic treatments..
Of the two, layout one is probably the best way to have it, but with some modifications..
Moving the screen out from the wall allows you to centre it on the room width..
This will reduce your first row distance slightly, but I think you'll have enough space to move it back a little..
This will then give you even side spacing for the surrounds, as shown on your drawing..for a much improved balance of sound..
You may have to supply just 2 seats at the back, otherwise the third seat will not be very nice soundwise..
