Which photo?

Today I bought a new (used) camera Canon 5d
This will fit bettwr with my current system with my main being a 5d2 and backup/secon 50 d (cropped) the 50 d is newer and has more mps but the 5d should make my work flow easier. which photo....
well I took this as one of the test shots in the shop, then measured out a potention size of my studio to be erected in the ajoining site at home and did test shots there re lenght and large family groups in a 6mx4m studio. Later went to a beach themed party and took a few photos there. but being the sentimental that I am I'll go with the test shot from my new camera.
