Beginner Gardening: Plant in the East or the West?, 1 by Dean_W

I'm planning on planting a vine. Please see pic below. I'll be making a trellis/ arbor. My question is should I plant on the East side or the West side of this pic? The East side is on the right hand side of the pic. I was kind of leaning towards the West side since it seems it might provide the plants more light. But since I already prepared the soil on the East side I was second guessing myself. Plus I would have to move some of the plants in the lower left hand corner of the pic to be able to plant there. Any help would be appreciated.
