My Blueberry Plants

The top picture is the first blueberry plant growing in a full sun location and I can tell that it's growing exceptionally well. It has a little reddish tint to the leaves, as well.

This plant  is growing in an area of the yard that gets partial sunlight. The leaves are very vibrant green and the plant has definitely grown a lot. 

Wonder how differently these plants will grow being placed in different sunlight conditions. 

Which plant will grow better the top one or the bottom one?
