Typically a N-S orientation will give you the most sun exposure. But with size of that lot, and a small plot you speak of, then either will probably work. The other consideration, is when you want it most produtive and what you are planting. If you want is good for summer in perhaps a clover, then some protection from heat would help, thus you should go E-W. If fall attraction is most important, then more sun later into fall would mean N-S orientation. The other Trump factor, is wind direction and how you want to pattern deer in morvement. Maybe a diagonal plot facing into the NW would be in order. Lots of variables. I have all the above on mine.
